I am a 40 year old woman who has been in great health. Last year I had 2 kidney stones. I do not have any now, but continue to get pains in my left kidney and urethra. Now I am experiencing pain in my lower back, on the right and left of upper buttock (not my spine though). i went to the doctor and they took an xray and a CT scan- nothing showed up. Also, I woke up on March 16th with very puffy eyelids...and they still are that way. Then both kidneys hurt and all of my joints started to ache. The doctor found a small bladder infection in my urine sample and gave me an antibiotic. It cleared up the bladder pain, and some of the kidney pains. But now my left kidney and lower back are in pain- the puffy eyelids are still there too. Please help me.
