I was diagnosed with kidney stones last December. now I get itchy on buttocks, lower back, and skull. There is a visible rash. The itching stops if I take Benadryl. It also feels like tiny insects are biting. Just burning sensation but no mark on skin on my ears, legs. It s random. We also adopted a labrador last October. Thank you!
Hi, the information which is available here is little incomplete. You mention 2 important hints-first kidney stone and itching. Itching often related with kidney failure, so a complete medical evaluation is required including renal function test. However, this problem can be seen in primary skin disease which require dermatology opinion.
