Doctor prescribed Lisinopril along with Metformin about a year ago , he told me the lisinopril will help protect my kidneys from the diabetes along with reducing my high blood pressure. I started with cramping and shaking which left me bed ridden for days! I blamed the metformin, thinking it was reducing my bodys sugar level. In this time I started having these pulsating, center of chest, waves of severe hot pain, I went to his office and he put me on an EKG machiene. Everything was fine. I have these bouts every so often, along with lip numbness and severe pain that feels like my right arm is caving in with muscle spasms, my veins stick out in the effected arm along with a numb cold feeling!(goose bumps too?). My physician told me it may be GERD.He put me on protonics which helped for a while, but it is back! I also get edgy,have trouble staying asleep and walk around like a zombie in a fog all day long. I started getting strobe light migraines without the pain recently, wondering if anyone else has had these symptoms from Lisinopril? By the way my blood sugar is in control. Also on allopurinol with no problems.
