Cold sores alternatively known as fever blisters is a viral infection, which usually occurs around the mouth.They occur in patches and heal within 2 to 4 weeks usually without leaving behind any scars. Cold sores are contagious and can be spread from person to person via close contact. Read on more to find all about them.

Symptoms
Usually cold sores passes through multiple stages
1. Tingling and itching: People usually experience a tingling, burning sensation around the lips prior to blisters, which may appear within a day or two after such a sensation.
2. Blisters: These blisters are small, filled with fluids and usually break out along the border of the skin and the lips. They can also occur around the nose or cheeks.
3. Oozing and crusting: The blisters have a tendency to burst which leaves shallow open sores which then usually crust over.

Some other symptoms, which accompany cold sores are fever, headache, sore throat, muscle aches and swollen lymph nodes.

Causes
Strands of the herpes simplex virus (HSV-1) typically cause cold sores. In some instances, HSV-2 can also cause cold sores. Cold sores are most contagious when they are in the form of oozing blisters. It can spread by sharing the same utensils, kissing, sharing towels and razors and also oral sex. Cold sores can be triggered due to several factors such as stress, fatigue, fever, hormonal changes and changes in the immune system.

Risk Factors
About 90% of adults worldwide test positive for this virus. People who have a weakened immune system are more prone to be infected by the virus. For example people suffering from eczema, AIDS and severe burns have a higher chance of contracting cold sores.

Complications
In certain cases,cold sores affect other parts of the body. Fingertips, hands, and some other parts of the body are affected by both HSV-1 and HSV-2 in some instances. It can also cause eye infections, which can lead to blindness or may even spread to the spinal cord and the brain in people who have a very weak immune system.

Treatment
Cold sores have no treatment and they usually clear up without any medication within 2 to 4 weeks. However certain antiviral medications are present which speed up the healing process.

All About Cold Sores

Hives are a common allergic reaction that appears in the form of swollen, red bumps or patches on the skin. These usually appear suddenly and cause itchiness. In some cases, it may also sting or burn. Hives can affect any part of the body including the face, ears, tongue, lips and throat. Hives are usually small in size but may grow as large as the size of a dinner plate. In some cases, hives may also join together to form plaques.

Hives are caused as a result of the production of histamines in the body that make plasma leak out of blood vessels in the skin. These histamines are released as a result of an allergic reaction, exposure to chemicals, insect bites, sunlight or adverse reactions to certain medicines. There are four main types of hives:

Acute Urticaria: These hives usually last for less than 6 weeks. They are triggered by insect bites, allergic reactions to food, latex, medicines or by exposure to infections. The most common food items that trigger this type of hives are chocolates, nuts, fish, tomatoes, eggs, soy, wheat and milk. Aspirin and other medicines like ibuprofen, ACE inhibitors and codeine can also trigger these hives.

Chronic Urticaria: Hives that last for longer than 6 weeks fall into the category of chronic urticaria. IT is harder to find what triggers a case of chronic urticaria than it is for acute urticaria. Along with the triggers mentioned above, hormonal disorders, tumours, chronic infections and immune system disorders can also trigger these hives.

Physical Urticaria: Hives caused as a result of physically stimulating skin are called physical urticaria. This includes sudden exposure to heat or cold, sunlight, vibrations, pressure, exercise etc. These hives usually resolve themselves within an hour and only affect the part of the skin that has been stimulated.

Dermatographism: Hives caused by scratching or firmly stroking the skin fall under this fourth category.

Hives can also be genetic in nature. Some people suffer from hereditary angioedema which is a painful swelling under the skin.

Hives caused by an allergic reaction can recur and hence if you suffer from hives you should try and identify the allergen. This can be done by taking an allergen test in a hospital or by changing aspects of your diet and studying the results. Hives are usually treated with antihistamines but in some cases, steroids may also be needed. However, it is usually nothing to worry about.

What Are Hives? What Causes Hives?

Testosterone is often the subject of jokes but an insufficiency of this hormone is no laughing matter. Along with affecting your sex drive, low levels of testosterone can also affect your ability to concentrate on tasks, lead to high blood pressure and cholesterol. Additionally, it can increase your risk of obesity and type 2 diabetes. Here are a few signs that could indicate low levels of testosterone-

Decreased Libido: With age, you may experience a lowered libido but a sudden decline in your sex drive could be caused by a lack of testosterone.

Erectile Dysfunction: Lowered levels of testosterone in the body can affect the release of nitric oxide necessary for an erection. Men suffering from lowered testosterone levels often find themselves either not able to have an erection or have erections that are not firm enough for intercourse.

Fatigue: Feeling tired at the end of a day is normal but men who have lowered testosterone levels may find themselves feeling extremely tired by lunchtime. You may also notice a loss of drive and enthusiasm.

Moodiness: Men with low levels of testosterone often become depressed and dejected. They feel less optimistic than normal and become more irritable.

Reduced Muscles: Testosterone is linked to muscle building and hence a lowered level of testosterone can be indicated by a reduction in the arm, chest or leg muscles. Men with low testosterone also find it difficult to build muscle mass.

Lowered Attention Span: Testosterone is responsible for focus and attention. Hence, trouble concentrating on work and memory problems can be seen as signs of lowered testosterone levels.

Development of Breasts: The lack of testosterone can cause an imbalance of oestrogen to testosterone ratio in the body. As the oestrogen levels get higher, men may find themselves growing breast tissue. This condition is also known as gynecomastia.

Bone Problems: A lack of testosterone can affect bone density. This may lead to osteoporosis like conditions and joint pains. Men with low testosterone levels are also more prone to injuries.

Lowered Semen Production: Testosterone is directly linked to semen production. The lower a man s testosterone levels, the lesser the amount of semen produced.

Hair Loss: Many men experiencing lowered testosterone levels suffer from hair loss on their head and other parts of the body as well.

The good news is that this disorder can be treated. Hence, if you find yourself experiencing any of these symptoms, consult a doctor at the earliest.  

10 Warning Signs of Low Testosterone

For a long time cholesterol in totality was seen as a bad thing for your body although the truth was a little more complicated than that. Cholesterol primarily is divided into two types, one of which can be categorized as bad cholesterol and the other as good cholesterol. Let's have an in-depth look at both the categories.

LDL or Low Density Lipoprotein aka bad cholesterol: Cholesterol is a wax like chemical, which is found all over the body and it has important functions to perform. Cholesterol is carried all over the body by Lipoproteins. The low density lipoproteins are denoted as bad cholesterol as they can accumulate on the walls of the blood vessels and cause blockages resulting in many ailments. LDL levels of 190 and above are considered dangerous. 

Some of the risks associated with it are:
1. Heart disease
2. Stroke
3. Atherosclerosis
4. peripheral artery disease among many others

HDL or High Density Lipoprotein aka good cholesterol: This is a form of cholesterol which is usually desired in higher quantities as it removes LDL from the system by dislodging it from the arteries and then carrying it through the blood stream into the liver. The liver then breaks it down and removes it from the body. Thus, higher number of HDL cholesterol is always desirable. 

Some of the ideal numbers for HDL cholesterol within the body are:

Women - Ideal: 60 mg/dl, dangerous: 50 mg/dl or lower
Men - Ideal: 60 mg/dl, dangerous: 50 mg/dl lower

The role of triglycerides
Good and bad cholesterol levels also depend on the levels of triglycerides within the body and not just LDL or HDL cholesterol. Triglycerides are another type of fat which are used to store energy within the body but can also affect your health. It is most associated with atherosclerosis when the levels of triglycerides are high within the body. 

Some habits that contribute to high levels of it are:
a. Lack of physical activity
b. Obesity or being overweight
c. Excesses in alcohol consumption
d. Smoking
e. Bad diet and others

Thus the good cholesterol versus bad cholesterol war also includes other factors, most of which can be easily changed by making subtle changes in lifestyle and incorporating healthier habits. This will increase the good cholesterol and the other relevant elements and reduce the bad.

Cough and Cold Due to Weather Change - Prevention & Treatment Tips

Do you switch off the lights a certain number of times before going to bed? Do you clean your windows even after they have been cleaned more than once in the day? Do you check your locks again and again before stepping out? If yes, then chances are you that are suffering from obsessive compulsive disorder (OCD). OCD is something which is difficult to overcome. However, the great thing is that it is not something that happens to be untreatable.

OCD is something which affects a range of people and to varying degrees. To some, it may have the effect of making their lives a little unusual, and to others it can go some way in greatly mitigating the pleasure they get out of living their lives. A person who suffers from OCD keeps on doubting his or her actions, especially when it comes to the possible repercussions of him or her not doing what he or she was supposed to do. This could include a person asking himself or herself whether he or she has put the gas off, or turned the tap off in the bath tub before to leaving the house.

Taking control of the obsession

In order to reduce the adverse impact that OCD has on the life of a person, it is important to exercise regularly. This is because OCD is an issue which has a lot to do with the nervous system, along with the brain, and the benefits of exercise on the nervous system can have a meaningful impact.
A lot of the problems a person experiences with respect to his or her health has to do with the amount of sleep he or she gets. It should really not come as a surprise in that case that it is not much different in the case of OCD. When a person does not get as much sleep as he or she normally should, it can cause issues by way of thoughts and ruminations in a mind that is not rested to an extent that is adequate.
Many people seek to control their OCD by trying to avoid the fears they face. However, it should be noted that this is not a good way to go about with it due to the fact that avoidance is very likely to compound the level of fear. Instead, a person who suffers from OCD should make an effort to follow a ritual which involves making sure whatever he or she is afraid of is incorporated in it.
OCD is something which has the potential to scare a lot of people. However, adequate effort and treatment can make sure that it no longer should.
