Itchy spots
by GiseleB, Jul 19, 2008 09:00PM
Lately, I have been getting quarter-sized itchy spots in random places on my body. The calf, the ankle, my side, and the latest ones on my back. They are very big and itchy and after 3 or 4 days, they turn into a brownish color and in the middle appears a tiny scab. I was thinking they were some kind of insect bites but so far I have counted 14 spots.
All the spots have appeared at different times and I really don't like going to the doctor but I want to know what this could be.

The big itchy welts are due to a condition called hives. Hives are red, itchy welts or swellings on the skin that often come in clusters. They can appear anywhere on the body, cropping up either in one small area or covering large patches of skin. They most often occur as part of an allergic reaction. No one lesion lasts more than 24 hours, but new ones may continue to appear until the condition resolves.
The scab in the centre could be either due to your scratching or it could be that the lesions are due to scabies.
Scabies is a skin infestation by the itch mite. They burrow into the skin to produce intense itching, which tends to be worse at night.
Scabies produces small red bumps and blisters and affects specific areas of the body. The bumps (medically termed papules) may contain blood crusts.
Treatment is with permethrin (Elimite) creams that are applied from the neck down, left on overnight, then washed off. This application is usually repeated in seven days.
Wash linens and bedclothes in hot water and all those who were in close contact with you need to be treated too.
You can take anti-histamines such as diphenhydramine (Benadryl) or Cetrizine which help in providing relief from itching.
This will help even if it is an allergic reaction. you can also try Calamine lotion or Pramoxine gel/lotion on the affected areas to provide relief from the itching.
