Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have symptoms of red itchy rashes on finger, hand, neck, upper chest and armpits. Well the symptoms you mention in query can occur due to many reasons like
contact dermatitis ,
allergic reaction due to detergent, soap , fragrance , chemical, metal such as in jewelry,
poison oak or ivy, an animal bite, and an insect sting. Need not to worry. You should avoid touching or pricking any rashes. You should wear loose clothes to prevent frictional heat produced in body. would suggest you to
consult dermatologist for proper examination . Doctor may prescribe antihistamine , corticosteroid ointment and immunosuppressants , anti inflammatory. Avoid touching or pricking rashes. For now take
benadryl twice a day , apply cold compresses , avoid direct sun exposure and avoid any cosmetic product .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
