I have been having upper back pain since I started this medication. In addition it has aggravated a shoulder problem that has bothered me intermittently for years. I am a 47 year old active male. I exercise 3 to 4 times per week and lift weights. I have had lower back pain in the past but never upper like this. since my activities have not changed with the onset of this pain I attribute it to the medication. It started after I started this medication. Cholesterol was up to 260 so doctor prescribed zocor 20mg to lower it. I have been on this for six weeks and head back for a recheck next Tuesday. I am hoping it is low again so I can get off this drug.
