Hives, also called urticaria are swollen welts or bumps that appear on your skin suddenly.

They itch, burn and sting and can happen anywhere on your body. You can get them on your face, lips, tongue, ears or chest. And in size, they can be as small as an eraser to as large as a plate. They also form plaques and can last for hours or up to several days.

Types

Acute urticaria - These type of hives last less than six weeks. The most common causes are allergies due to certain foods and medications, or infections. These hives can also happen due to diseases or insect bites.
Chronic urticaria - Hives lasting more than six weeks come under this category. What causes them is usually more difficult to identify than what causes acute urticaria. In some cases, chronic hives are caused due to thyroid disease, hepatitis or even cancer. This type can affect your internal organs like lungs, muscles, and the gut. Thus, symptoms include muscle soreness, shortness of breath, vomiting, and diarrhoea.
Physical urticaria - These types are caused due to direct physical stimulation of the skin due to cold, heat, sun exposure, vibration, pressure, sweating, and exercise.
What causes hives?

Hives happen mostly due to allergies. Some of the common hive triggers are-

What Are Hives? What Causes Them?

We grow up thinking of our nails as dead cells and pay attention to them only to trim them once a week. If you re a woman, this might extend to painting them in different hues. However, the shape, texture and natural colour of your nails along with the rate at which they grow says a lot about your overall health.

Homeopathy is an effective way of treating nail disorders as it addresses the root cause of the problem. This form of treatment has negligible side effects and hence, can be used over a long period of time. However, homeopathy should never be used to self medicate. This is because a homeopathic prescription depends on the symptoms presented and the personality of the patient.

Here are a few changes in your nails that could be signs of health disturbances.

Horizontal ridges: White horizontal ridges across your nails are developed when there is a pause in the growth of the nail. They could be an indication of an injury or a symptom of a serious illness. These are also known as Beau s lines or Mee s lines. Beau s lines are developed due to psoriasis, diabetes, circulatory disease or a severe deficiency of zinc. Mee s lines can be a result of arsenic poisoning, malaria, leprosy, Hodgkin s disease or carbon monoxide poisoning.
Vertical ridges: This is a common sign of aging and is usually nothing to worry about. However, in some cases, it could be a sign of vitamin B12 or magnesium deficiencies.
Spoon nails: If the edges of your nails curve upwards and take on a spoon-like look, it could be a sign of anemia, excessive iron absorption, heart disease or hypothyroidism.
Pitted Nails: Dents or pits in your nails are usually a sign of psoriasis. It could also be a symptom of tissue disorders such as Reiter s syndrome or autoimmune diseases like alopecia areata.
Dark nails: If you notice dark,discoloured patches on your nails, consult a doctor immediately. This could be due to melanoma which is the most dangerous form of skin cancer.
Yellow Nails: Smoking and excessive use of acrylic nail polish are the two most common causes of yellow nails. However, if your nails are thinand crumbly along with being yellow, it could be a sign of a fungal infection. In rare cases, yellow nails could also be a sign of thyroid disorders, diabetes or psoriasis.
Clubbing: Nails that are enlarged and curved downwards are said to be clubbed. This is typically a sign of low levels of oxygen in the blood. It could also be symptom of lung disease, liver and kidney disorders, AIDS and inflammatory bowel disease.

Nails - Can They Indicate Any Illness?

Depending on the way you look at it, a mole can be a beauty spot or a blemish. For most people, facial moles are undesired. Moles can be described as clusters of pigmented skin cells. They appear in the form of dark spots on the skin that vary in size, color and texture. Apart from the face, moles appear commonly on the arms and legs but can affect any part of the body. In most cases, moles are harmless but in some cases, they may turn precancerous and need to be removed. However, most moles are removed for only cosmetic reasons. Moles can be removed through home remedies, surgery or laser treatment.

Mole removal depends on the type, size and location of the mole. When treated with lasers, layers of the mole are removed one by one by evaporating the affected cells. This does not cause any sort of bleeding and does not disturb healthy tissues adjacent to the mole. It is also considered to be a largely pain-free procedure but you may feel a slight tingling sensation. After the laser procedure, a scab forms over the affected area which later falls off. You may also notice slight swelling and redness in the area for a few days after the procedure.

Laser treatment for mole removal has a number of advantages.

As it is a non-invasive procedure, there are minimal chances of infection
Multiple moles can be treated in a single session
Laser beams can reach parts of the face, nose and ears that may be difficult to reach through other procedures.
There are minimal disturbance and injury to the adjacent healthy tissues
Healing is much faster than with other procedures
There is a very low chance of scarring
However, one of the biggest disadvantages of laser therapy is that it can only be used to treat surface moles as the laser beam cannot penetrate deep into the skin. Also, laser treatment, if not recommended in cases where the mole may be considered precancerous as the laser beam will destroy the mole leaving nothing that can be used for a biopsy. Lasers are also seldom used to treat large moles or birthmarks. The cost of removing a mole with laser treatment depends on the size, location and number of moles. In some cases, more than one session may be required and this too could influence the cost of the procedure.

Moles - How Laser Treatment Can Help You Get Rid Of Them?

Lymphedema is a condition that typically affects the arms and legs. The most common cause of this condition is damage to the lymph nodes or their removal as part of a cancer treatment program. There is no known cure for this condition. However, surgeries such as Vascularized lymph node transfer surgery may help deal with it better.

Vascularized lymph node transfer surgery involves replacing the affected lymph nodes with healthy lymph nodes from other parts of the body. This allows blood to flow more easily and restores or augments the lymphatic drainage system. In most cases, the healthy lymph nodes are harvested from the patient s groin. This procedure is relatively new, and its limits are still being explored by doctors. In cases of breast cancer that causes lymphedema in the upper limbs, this procedure may be performed along with breast reconstruction.

To be a viable candidate for this procedure the patient must have maximized control over lymphedema through other forms of lymphedema therapy. This therapy will need to be restarted after the surgery to ensure good results. The lymphedema diagnosis should also be less than 5 years old such that the patient s lymphedema is in its early stages.

As with any other surgical procedure, there are certain risks associated with this procedure. These can include

Reaction to anesthesia
Bleeding
Infection
Scarring at the site and poor healing
Damage to adjacent blood vessels
Nerve damage that can cause a temporary loss of sensation
Muscle weakness
Numbness ta the sites from where healthy lymph nodes were harvested
Risk of Lymphedema in the area where the lymph nodes were harvested from
After the surgery, the patient will need to keep pressure off the site where the lymph nodes have been transferred. The surgery site may be bandaged but compression garments will not need to be worn. On being discharged the patient may resume normal activities such as driving and work. High-intensity exercises that involve the use of the operated limb should be avoided for at least a month after the surgery. Compression garments should not be used until recommended by the doctor or a minimum of 2 weeks post-surgery. They will also need to schedule review consultations with the doctor. The schedule followed usually involves check-ups after 2 weeks, 1 month, 3 months, 6 months, 9 months and 1 year.

Dry skin is a condition caused by the lack of moisture in skin. Fine lines and wrinkles are just some of the conditions, which may be caused due to dry skin. Dry skin can also be very uncomfortable. The condition is mostly caused by environmental factors such as exposure to harsh weather conditions or getting soaked in hot water.

People at risk:
1. Age: People who are older than 40 years of age tend to be more at risk of dry skin than people who are younger than 40 years.
2. Climate: As mentioned earlier, weather conditions play a pivotal role in causing dry skin. Therefore, people who live in areas where the climate is either very hot or very cold tend to get dry skin more often than people who live in temperate climates. Low humidity is another factor which causes dry skin.
3. Profession: Some professions, such as nursing or hairstyling requires frequent usage of hot water all through the day, which can also lead to dry skin.
4. Swimming: Swimming is one of the major causes of dry skin. This is especially true in pools, which have chlorine. This is because chlorine increases the itchiness on your skin.

Treatments:
1. Lifestyle changes: Usually, lifestyle changes such as avoiding long, hot showers and putting moisturizers are good enough to make sure that dry skin goes away.
2. Lactic acid: Creams with lactic acid and urea can be prescribed by your doctor, if the dryness of your skin does not go away with moisturizers. These creams are usually over-the-counter medications.
3. Prescription creams: Prescription creams are given, only when conditions such as dermatitis, psoriasis or ichthyosis are present.
4. Wet dressing: Wet dressing is given only when dermatitis has set in, as it mostly help in preventing the infection.
4. Oiling: Oiling your body, especially with fish or flaxseed oil, ensures that your body does not succumb to dry skin.
5. Hand sanitizer: Normal hand sanitizers tend to make your hands dry. Thus, dermatologists recommend hydrating hand sanitizers that allow your hands to maintain their moisture. Therefore, whenever you are using a hand sanitizer, use a hydrating one.
