I was taking Lisinopril for a month. I am a 38 year old male. My fingers on my right hand and joints began to ache and swell up which is making them weak and painful to grasp anything or make a fist. I never had these symptoms until I started taking this medication. I continue even after stopping Lisinopril for the last 5 weeks. Now my doctor is thinking I might have Rheumatoid Arthritis. It takes 4 weeks for this Lisinopril to work. Which is bringing me to think this medicine caused me to have these problems by triggering something in my system. Has anyone else had these problems with this medicine?
