What causes spreading, itchy rashes on skin below the wrists?
Patient: Hi,  I came to Chennai in July. Last week I developer rashes on skin below wrists on both hands. I sweat heavily and there is itching on the spots. There are small patches turning red now and today are a little higher and looks like they are spreading. Doctor: Hi,From history it seems that there might be having some allergic rashes might be due to some systemic allergen or local allergies due to handling some chemical or using some thing giving rise this allergic reaction.Take Benadryl or levo-cetrizine medicine for 2-3 days.Apply Caladryl lotion locally.Ok and take care.
