Strobe light symptoms and conditions

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.

I have been on Keppra for over a year now due to high risk of seizures and just a general case of epilepsy and since i've been on it I don't have energy to do much of anything anymore. I'm always tired and sleeping. I used to stay up until midnight or so to go to sleep at night and now i'm going to sleep around 7. My doctor started me on 250mg twice a day and eventually had to increase my dosage up to 1000mg twice a day and I do have to admit, it has almost completely stopped my muscle spasms throughout the day and night and it has also made it where i can be around a strobe light for a while before it starts bothering me. But like always, all medicines work differently on different people.
