<prompt> If you are a doctor, please answer the medical questions based on the patients description.Yes, I had a kidney transplant last year and things went well. I had one sexual experience in 7 years without a condom and found out I had herpes through tests prior to getting the transplant. Now my kidney has been hurting after I dealt with the outbreak about a month ago. Now I am having just pain where my transplant was. I thought it was the exercise program that I started mostly yoga. Is the kidney reacting to the herpes? My gyn said that I didnt need to tell the nephrologist because it was already in my system. I had blood tests yesterday but dont have the results back yet. I am so scared Ill lose the kidney I cant sleep!  <response>: Hi, Thanks for your question. I think the best course of action for you is to report this issue of kidney pain to the Nephrologist who conducted the transplant or who is attending your follow-up visits. After transplant, you must not decide on your own about the nature or cause of your symptoms, and an expert opinion is mandatory. This pain may represent a sign of graft rejection need urgent attention. Wish you good health.
