I have been taking Lovastatin for going on 6 days now. I am having little twitches in my arms, legs, eyelids, and the corner of my mouth. Additionally I am having a very bad burning sensation in my right chest and back. I don't know if it's heartburn or not. I have pretty bad functional dyspepsia and now I am getting small painful stomach cramps every now and then. I'm only 18, I don't see why the doctor didn't just prescribe diet and exercise. I also take a daily multivitamin, fish oil capsules, and Prilosec. I'll call my doctor tomorrow, but if the burning gets worse I am going to the ER! Thank you for your help.
