Foam roller symptoms and conditions

I have been on Simvastatin for about 4 months now. For the past 2 months, I have been having unexplained muscle/joint pain and tightness in my hips and thighs. I couldn't figure out what I'd done but thought it was just one of those things (slept wrong, stepped wrong, etc.). I've been working with a foam roller to get the knots out, even getting up in the middle of the night to work on the roller because it hurt so much. That helped some. Took Motrin but that didn't work at all! Added Omega 3 fish oil and glucosamine and that did help a little. Have been limping for 2 months now and it finally occurred to me, "I wonder if it's the Simvastatin?" I already knew I was sensitive to chemicals like sodium lauryl sulfate, so everything I see written here makes sense to me. I emailed my MD today and she said to stay off it for 3 weeks and see if I see any improvement, plus get blood work. I sure hope I don't have any muscle damage. Thank all of you for posting your experiences
