This is likely to be eczema.
The exact cause of Eczema is not known, but it is believed to be an immunological disease. These episodes are believed to be set off by some irritant contact, like rubber in some people, but rarely is such an irritating agent found. In most cases, like in yours, the eczema attacks appear to be set off spontaneously. Sweat retention is also believed to be an irritant in many. Still, you must try to analyse whether there is anything which sets off these attacks.
The mode of treatment is:
Antihistaminic: Take an antihistaminic like Cap. Claritin one cap twice daily
Avoid sunlight: This is most important. Avoid going out into the sun as far as possible. If you have to go out, use a wide brimmed hat and long sleeved dresses and pants. Sunscreen is a must – use sunscreens with 50% SPF or more.
Steroid Ointments: These are sometimes combined with antibiotic ointments. you can OTC preparations like 1% hydrocortisone or higher strength prescription steroid ointments.
Emollients: In case of dry skin, massaging an emollient such as a hand cream is useful in dry skin.
Avoiding the irritant: If some irritant can be identified, then it should be avoided.
In severe cases, after consulting a dermatologist:
Ultraviolet rays: PUVA treatment with ultraviolet rays can be givne for this.
Grenz Ray therapy: this is another form of light therapy which is very effective.
You can try these OTC treatments for now. They will give relief in most cases. However if the rashes persist or new ones keep appearing then you should show your doctor, preferably a dermatologist. This will give you a firm diagnosis and also you will be able to get prescription drugs. You should also discuss about light therapy with him.
Take care - wish you good health and a quick recovery. Stay safe.
