Muscle contusion is a condition that is characterized by bruising in the muscles. It generally tends to occur in athletes who play a lot of contact sports. Repetitive blows in any part of the body may cause damage to the underlying muscle tissues. These blows may lead to internal bleeding, resulting in blood clot formation. The most common site where it occurs are the quadriceps.


The various causes of this condition are:
1. Direct repetitive blows to a part of the muscle in contact sports such as football
2. If you fall on a hard surface 
3. It may also occur if the muscle comes in contact real hard with sports equipments like soccer balls

The symptoms of a muscle contusion are:
1. You may experience swelling of the muscle
2. Excessive pain
3. Decrease in range of motion in the concerned body part
4. It may lead to leaking of blood vessels
5. You may also experience hematoma where a lump is formed over the affected spot
6. Symptoms of broken bones, dislocations and fractures may also occur

Complications
This disorder may also lead to various complications such as compartment syndrome, which leads to compression of blood vessels resulting in pain. 

Treatment
The basic treatment for this condition is the rice protocol which is rest, ice, compression and elevation. You should rest the muscle, then apply ice to the affected area to reduce the pain. You can also take nsaids (non steroidal anti-inflammatory drugs) to reduce the pain. In severe cases, the doctor may drain the lump surgically.


It is advisable to not return to your normal sports routine in order to allow the muscle to recover. If you carry on with your regular routine, it may result in further complications like the formation of scar tissue. You may undergo various stretching exercises to relieve the pain and make a gradual return to your normal sporting activities.


Causes and Symptoms of Muscle Contusion

Runner s knee is a very common problem with athletes. It is definitely not something one needs to worry about. In fact, with certain exercises, it can be prevented and if you do develop a runner s knee, it can be treated with some exercises as well. There are special sports medical practitioners who prescribe not only regular physiotherapy, but also specific exercises to deal with specific sports injuries.

Runner's Knee - 4 Most Important Exercises for it

After a tough workout session or a strenuous day at the office, your muscles may feel floppy and exhausted until you have given them a chance to rest. However, persistent muscle weakness with no apparent cause or explanation can be a sign of an underlying medical problem.

What causes muscle weakness?
Voluntary muscle contractions and movement are generated when the brain sends a signal through your spinal cord and nerves to the particular muscle. If there are any hindrances in the connections between them, it can result in muscle weakness. However hard you try, the muscle is such cases becomes abnormal.

Here are some common causes of muscle weakness:

Lack of Use: One of the most common causes of muscle weakness, lack of muscle fitness may occur as a result of a sedentary lifestyle. If the muscles are not used, then the fibers are partially replaced with fat.
Ageing: As we age, our muscles tend to get weaker and lose strength. Muscles become bulky and recovery times during injury are greater. However, with physical activity, it is still possible to increase the muscle power. So stay active and instill strength in your muscles.
Infections: Infections and inflammation can cause temporary muscle fatigue. Even though recovery is quick, if the infection is severe the weakness can last for some time. Without proper care, it can lead to permanent damage.
Pregnancy: During and just after pregnancy, high levels of steroid in the blood and low levels of iron can cause muscle tiredness. Lower back pain is common during pregnancy and all your muscles may feel floppy.
Chronic Diseases: With conditions of diabetes, heart disease, kidney disease and anemia, it can lead to muscle weakness by thwarting the essential blood or nutrient supply to the muscles. Also, chronic pain related ailments cause weakness.
Injuries: Injury or trauma such as sporting injuries, pulls and sprains can deter the muscles. Along with localized pain, it can also lead to muscle weakness if not taken care of properly.
Sleep Disorders: With disturbed or reduced sleep there is a general sense of tiredness that leads to fatigue in the muscles. Insomnia, anxiety, depression and other mental disorders also affect the muscles a great deal.
Conditions affecting Nerves: Conditions like Myasthenia gravis or motor neuron disease affects the nerves and thereby fail to relay signals to the muscles, leading to weakness.
Genetic disorder affecting muscles: There are also certain inherited diseases which can affect the muscles like muscular dystrophy.
Spine-related disorders: Conditions like slip disc and other disorders affect the muscles served by the irritated or compressed nerves of the spinal cord.

Muscle Weakness - 10 Common Reasons Behind It!

Bones and muscles, together known as the musculoskeletal system, are responsible for all bodily movements. The bones and muscles move in unison, as they are connected by what are known as tendons, which are thin fibrous tissue. These tendons are prone to damage and inflammation known as tendinitis (this can cause inflammation in any organ). It can occur in any bone/joint but most common in areas which are prone for repetitive use including the wrists, arms, elbows, shoulder, knees, and ankles. 

Read on to understand how it happens and how it can be managed.

Causes: Depending on the onset, tendinitis can be acute or chronic. Though it can occur in any individual, the risk increases with age, as bones lose their elasticity and can tear.

Acute is caused by a sudden injury like a fall or accident or infections
Chronic is caused by repetitive movements, poor posture, poor stretching, overuse, etc. Some common movements include carpentry, painting, golfing, tennis, gardening, lawn mowing, badminton, etc.
Symptoms: As with any inflammation, the symptoms of tendinitis would include swelling, pain, redness, and warmth. There is also a reduced range of motion of the affected joint, producing what is known as adhesive capsulitis.

Prevention: Tendinitis is preventable to some extent by avoiding repetitive work and overuse of the joint. Those who are used to a lazy week and an active weekend should definitely watch out. Sudden, excessive stress can cause tendinitis. The tendons should be subjected to limited stress and activity. With any kind of activity, if there is even a slight hint of pain or any issue, get it checked with the doctor. Continuing to do the same activity will only make it worse. Symptoms to watch for include fever, swollen and painful joints, and limited movement of the affected joint.

Management: If identified and arrested in the early stages, tendinitis can be managed conservatively. Progressive measures of treatment would include the following.

As soon as there is discomfort identified, rest the joint and stop any activity, which you think could have caused the problem. Usually, this should help the condition to subside on its own. Ice and heat therapy can also help.
If it is the ankle or the knee, keep it elevated.
Pain killers may be taken if the pain cannot be tolerated or is affecting daily routine.
After the initial week, mild exercises to strengthen the tendon can be started.
Steroid injections may be required in cases where the joint pain and swelling is significant.
As a last resort, if the above measures do not work, surgery may be recommended. This will again be followed by rest, medications, and physical therapy.

Tendinitis - Ways It Can Be Managed!

Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision. 

Hot & Cold Therapy - How It Can Treat Pain?

When we speak of bone health, calcium is usually the hero of the story. However, by itself, calcium is not enough for healthy bones. Vitamin D is equally important for healthy bones and the prevention of orthopedic conditions.

What does Vitamin D do?
Vitamin D helps the body absorb calcium from the food being eaten. It also controls the calcium and phosphate levels in the body. This is critical for the growth and development of new bones. Vitamin D also controls how much calcium and phosphates are being expelled by the body. In this way, vitamin D helps strengthen the bones and improve overall bone health.

Vitamin D Deficiency
Vitamin D is not commonly found in food. It is present only in certain types of oily fishes, egg yolks and mushrooms. Most of the vitamin D we eat comes from fortified cereals, breads and dairy products. The sun is an important source of vitamin D but exposing yourself to too much sunlight could cause various skin problems. Thus, vitamin D deficiency is very common. When it comes to bone health, vitamin D deficiency can cause low-density bones. This, in turn, can cause rickets and osteoporosis. People with vitamin D deficiency are likely to suffer frequent fractures. Vitamin D deficiency can also cause skeletal deformities such as bow legs and a stooped spine.

Vitamin D and Osteoporosis
Osteoporosis is a musculoskeletal condition that is marked by low bone density. Studies have shown that people with osteoporosis have lower levels of vitamin D as compared to others. Some studies also suggest that fractures are more common in winter as compared to summer. The winter sun is often hazy and many days can go by without strong sunlight. Thus it can be inferred that people do not get their required quota of vitamin D from the sunlight in winters leading to a deficiency and aggravated osteoporosis-related fractures.

Who is most susceptible to bone conditions caused by vitamin D deficiency?
Vitamin D deficiency is a very common condition across the globe. Some surveys have claimed that approximately 30% of the global population suffers from vitamin D deficiency. People with dark skin, women and elderly people are most susceptible to this deficiency. People suffering from kidney diseases may also be affected by vitamin D deficiency. Vitamin D supplements are usually very helpful in combatting this deficiency. These can be taken by young children as well as adults.
