Lipitor and dull headaches

I've been on lipitor and other generic forms of it for the last 8 years since the age of 26. I started on 10mg then 20mg and later 40mg. About 4 years ago I started with severe stomach cramps. The pain is so bad that I have to go home in the middle of the day, I can't walk or sit straight the pain is that bad and NOTHING helps. On a scale of 1 to 10 I would probably put this at a 7 or 8. I would also be nauseous and be really tired. I have had countless opinions and tests done and doctors keep telling me it is an "enigma" and there's nothing wrong with me. We've treated it through coeliac diet, exercise, lots of water, but it never helped. About a week ago I stopped drinking my meds by pure chance. I have not had one incidence of stomach ache. My doctor tells me that it's not possible for the lipitor to be the cause. I am sure he's wrong. Has anyone had a similar experience?

I am 47 and have been on Lipitor now for about 7 months. For the last week or so, I have been experiencing upper shoulder, neck, and elbow pain. I passed it off as possibly the way that I sit at my computer. 1 week ago I went to the doctor to have the normal liver blood tests and she (the PA) asked if I had been experiencing any pain in my legs. At the time I didn't, and I didn't think anything of asking about my upper shoulder and neck problems, so I said "No, I feel fine".
Now today, I have been experiencing a constant twitch (for the lack of a better term) in my left foot. It's not like a normal twitch, in fact when my husband asked me to describe the sensation, I said that it felt like my nerve endings were twitching. I have also had a lot of dull headaches lately (which is very uncommon for me). I decided to search for Lipitor side effects and found this site. The thing that worries me more than anything is that my mom (which is 80 years old) has been on Lipitor now for approximately 4 years. She complained of her knees hurting but, chalked it up to her age. She contacted the doctor and he said that it wouldn't cause the kind of pain she was describing. It was most likely due to her age. I am so thankful I found this site and that everyone has taken the time to share their story. I am hoping that there is a healthier alternative. I read somewhere (maybe this site) to start taking CoQ10 and Vitamin C to reduce your cholesterol naturally. Hope this helps. Also, your natural CoQ10 is reduced considerably when taking statins. Thank you to everyone that has posted here. If I hear anything new I will let you know. God Bless and best wishes to everyone.
