I have a rash on my shoulders and down my back somewhat. Read an pimply. I have had it for about 5 days. I used cortisone and bendryl but it is still present. Now, I feel like Prickly sensations all over my body, not just on the rash.  I have very sensitive skin and I am allergic to soaps, detergents, etc. I am also allergic to plants and stuff. I was camping last weekend. Did I brush up against something? WHAT IS THIS? HELP! Thanks!
Hi Dear, Understanding your concern. As per your query you have symptoms of red rashes on shoulders and pricking sensations all over the body which is known as demographic urticaria which could be due to increased skin sensitivity and compromised immunity of body. Need not worry. I would suggest you to apply cold compresses to the affected area. Avoid sun exposure. Apply broad spectrum sunscreen with SPF 15 even if you are not under sun exposure. Take over the counter anti-allergic Chat Doctor.
