I have had pain in the left side of my abdominal area near the waist but several inches above the hip.Applying pressure to relieve the pain causes chills and temporary relief but causes a numbness in my brain suddenly. The sensation is accompanied by mild headache type pain and is brief. I alsosmell a combination of urine and ammonia. The numbness is sensed close to the center of my brain gradually fades as the fragrance does. My side, Brain, and sinus are affected during this cycle. Do I have a common problem or internal injury. What should I do?
Hi, Welcome to Chat Doctor forum.  You have got pain in the left lumbar area. The cause may be due to the urinary tract infection, or a stone in the ureter. It may cause the Chat Doctor.  The smell also can be due to the infection in the nose.  The renal colic will be associated with the fever, so may be associated with the headache.  You may need to have an M.R.I. for diagnosis. So I advise you to consult a urologist for diagnosis and treatment.  Wishing for a quick and complete recovery. Thank you.
