I was so happy to find this website!.. I am a 49 year old female taking Linsinopril for approximately 10 months now for high blood pressure (which has come down to a normal rate since being on the medication). I have been experiencing a severe in my lower back towards my left side for about 2 months now and have been tested for many things (ultrasounds, MRI's, blood work, etc.) and nothing has been found to be causing this pain so far. The pain is constantly there, but more severe when I have a bowel movement and for about 1-2 hours afterwards. I also have the following symptoms: pain in joints on left side of my body - ankle, hip, shoulder, elbow, wrist and hand (including joint swelling mostly on left side). Bad pain and weakness in upper left arm when I try to rotate my arm backwards - can no longer pick up heavy objects with left hand. Also have pain in joints on right side, but not as severe. I have experienced headaches and my abdomen feels swollen all the time. It feels as though someone pumps air into my stomach every morning. It also feels as if something is throbbing or on fire across my abdominal area. This condition has disrupted my life - I have no energy and feel weak and tired all the time. I get out of breath easily just from walking or any amount of exertion. I no longer have the ambition to do the things I used to do. I've been thinking that there has to be something seriously wrong that the medical doctors are missing - and have feared some type of cancer. Now that I have found similar symptoms on this website, I am going to try to stop the Lisinopril and see if my symptoms subside.
