Why do I have an itchy rash? Could it be an allergy?

You may be having an allergic reaction on your hands and legs. Common symptoms of an allergic reaction include redness, itching, and swollen skin. Allergies can be caused by various things such as certain foods, insect bites, or plants. You can, in turn, use a soothing lotion and take medication for antihistamines to cope with the symptoms. 

A person with chickenpox has a sore throat as a common difficulty. This phenomenon is from the throat's being irritated due to the virus. The good news is that the sore throat gets better as the body fights off the virus. Drinking warm liquids and soft foods may work well to soothe the throat. If the sore throat is severe or lasts a long time, it's important to see a healthcare provider for further advice.

Tanning is produced by the skin when it absorbs more sunlight. This is the process that involves melanin, a protein that protects the skin. To decrease tanning and melanin, try a kojic acid soap. This soap can decrease the melanin in your skin and thus brighten your skin's color. For best results, use it daily.

Skin melanin treatment surgery can be harmful in the long run so I suggest not to go for it. You can try other treatments like chemical peels or dermabrasion instead. These treatments can help lighten the skin and are not harmful in the long run. Also using moisturizer and sunscreen can help.

Your description of the symptoms leads me to believe that your mother has a skin condition called eczema. Eczema is characterized by the appearance of red, itchy patches on the skin. It can be caused or aggravated by certain substances or environmental factors. To alleviate the symptoms, it is necessary to maintain the skin's hydration and avoid irritants. Using mild soaps and wearing comfortable, breathable clothes can also be helpful.
