What Causes Severe Muscle Pain After Taking Lovastatin?

I took lovastatin for a couple years and then became very sick with severe muscle pain and extreme weakness. There were days I could hardly walk. Was unable to even Swiffer floors. Generally I was a very active 65 yr old male walk 5 and 10 K once each per week. Kayaking 4 to 5 mi once a wee and riding my bicycle 20 to 30 mi once or twice per week. All of that stopped! I then was changed to Crestor and my symptoms continued. Went to a neurologist and found some deterioration of lumbar region and also in neck. Got steroid shots and also a nerve block for left leg pain. Helped but not well. Then my dr. after 2 years figured I had peripheral neuropathy b/c I told him my toes hurt while in the recliner so I had to take off my socks. Anyway, I m on gabapentin with 100 MG taking 2 in the AM one at 3 PM and 2 at bedtime. 90% relief! However, my energy level is not what it was. Yes, I m 2 years older at 67, but after a bike ride I need to hit the recliner for a couple hours and I sleep 75 % of it. My total Cholesterol is at 245. Tri s 86, HDL 43, LDL 185, VLDL 17 and Ratio of HDL is 5.7 my dr. wants me to go on Lipitor at 20 once a day. I am so reluctant.. I m thinking of doing 20MG every other day to see what happens. I can t afford any more damage to my nerves... What do you think?
