I have been experiencing sharp pain in lower back, left side, for about 2 days.  Today I developed numbness in lower left abdomen that is increasing in size and I am now experiencing pain in lower abdomen. I had a massage therapist help today. She felt that something was not right and also noticed that my rib cage is very tight. The pain is increasing along with the numbness.
Hi, Welcome to Chat Doctor forum.  You have sharp pain in the left lower back, today pain and numbness in left lower abdomen.  Usually the pain suggests that there may be urinary tract infection, or a stone in the ureter near the bladder.  I advise you to consult a urologist for diagnosis and treatment. You may need to have M.R.I. for confirmation.  I usually prescribe to my patient with such symptoms lifetime, fanatic acid, dicyclomine HY Chat Doctor.  Wishing for a quick and complete recovery. Thank You.
