Thank you for your reply.
Yes,the symptoms you have described of raised rashes on both arms and now spreading to other parts of body is suggestive of skin disease known as eczema(Dermatitis)
A hypersensitivity reaction (similar to an allergy) occurs in the skin, causing inflammation. The inflammation causes the skin to become reddish & mild itchy. It is quite possible to get this allergy from a contact of some plant or an insect.
The following will help you greatly:Take tablet benadryl once a day.Apply cream containing hydrocortisone.
If the area is large then apply Calamine lotion.This will reduce the rashes & the slight itching you are having.All these medications are available at your counter without any prescription.
If still the symptoms persists or if the rash is severe, is on the face or genitals, or covers more than 20% of the body, then you need examination from your doctor & hence the prescription medications.
Usually & in most cases,the symptoms get resolved by this above described treatments.Also you do not have any rash on chest,face or legs so far.
