<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a terrible case of hives, but dont know what I got in to. Ive retraced my steps from yesterday but cant pinpoint any changes or new products. Now, my tailbone is very sore. I went to urgent care this AM and am now taking Benadryl and Pepcid AC, but the tailbone is a new symptom. Any ideas?  <response>: Hi and thanks for this query. I have reviewed the information you have provided and the treatment. This is good and well adapted for the allergic reaction that you developed. I will recommend that you carry on with the treatment. Should the pain persists, try some TylenolIbuprofen for relief as recommended by your pharmacist. These symptoms would soon regress. Please, exercise some patience! I hope this ad Chat Doctor. If you have any ore questions or need more clarifications, I would gladly do so. I wish you the best of health.
