Zocor and pain in the neck

I have been taking Zocor for over 4 years after having problems with Lipitor. I have recentley developed muscle and joint pain in the neck, shoulders and elbows and sometimes in the knees and legs. I have a great amount of fatigue and general weakness at times. Occasionally, I have a pale colored stool. I have also noticed a loss of muscle mass particularly in my arms. I am also experiencing easy bruising. After reading these testimonials, I am discontinuing Zocor to see if the problems improve. I am a 61 yr old male.

I'm a new userid of Zocor @ 20mg a day. 53 year old male.
I have a past history of multiple low back disc bulging against the spinal cord and problem with two vertabra in the neck. I have over come the leg and low back pain. I still have pain in the neck and left arm.
A 1.75ml of scotch last me about 4 days. Never a hangover or head ache. I'm a smoker too (1 pack/day).
I have no history of head aches save for a very infrequent sinus congestion/infection.

This is day five of Zocor for me. I slept well but as soon as I arose and had my normal glass of water, my sinus swelled up and had a head ache all day. I have no idea if was caused by the many places I visited yesterday or the Zocor. It did get my attention.

I did not get any good info from my provider on what side effects to expect, so here I am. I'll be watching for what has been posted and I thank you all for sharing. I'll let you know what happens.
