Images of rashes caused by common skin conditions
From your symptoms the possibilities of allergic reaction and hives needs to be explored. Hives result from dilation of capillaries allowing fluid to leak out into the surrounding tissue, the epidermis.They are of two types:acute and chronic(when hives persist for more than 6 weeks). The most likely triggers for acute urticaria are allergies to pets, horses, latex and foods, such as shellfish and nuts,bee or wasp stings,allergies to medicines,Viral infections, such as glandular fever and herpes, dental and sinus infections, fungal infections, blood transfusions and vaccines.
The cause of chronic urticaria is often more difficult to identify. Most cases are called chronic idiopathic urticaria, which means they're caused by the body's unexplainable development of antibodies to itself (auto-antibodies).
Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps. Also keep the area well moisturized by applying non perfumed, hypoallergenic moisturizers. If the symptoms persist then topical and oral steroids may be needed for which please consult a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
