[|Human|] I have kidney stones, and one is stuck between my kidney and bladder. Going to have them blasted next week. Today   I started having a rash on the back of my leg, arm and now on my side going to my back. Is this related to my kidneys. Should I go to the emergency room now or ok to wait until the morning to see my PCP.
[|AI|]  Hi, I can understand the concern for rashes at the back of leg and arms. After reading your history it appears that you have developed either urticaria or Allergic contact dermatitis to some contact allergen. It is not related to your kidney stones so do not worry and correlate your stones with rash. I advise you to not pinch or pop the area otherwise these areas are very prone for getting secondary infection. For time being period you can apply steroid based cream such as mometasone or cortisone and take antihistamine tablet such as loratadine or cetirizine. Do not try to even touch or pinch the area as can cause more aggravation of the problem. Take care.
