Simvastatin I am 45 and have been taking statins for 5 years since having 3 heart attacks in a 4 day period.At first I was on Atorvastatin 10mg and didn't suffer any side affects,I was put on Simvastatin 40mg 2 years ago due to cost.Since then I suffer with very sore muscle pain down the length of my right arm.My GP keeps on prescribing painkillers and doesn't mention the fact it may be side affects of the Simvastatin.I find it sad that costs of drugs are the reason I am in pain.
