Knee problem symptoms and conditions

I have been on Simvastatin for 11 months and have gained 46 pounds. I also am having problems with my knees joints and wake up 2 to 3 times a night. My Cardiologist told me weight gain is not a side effect of this drug but I'm not so sure. He also said my knee problem is a result of the weight gain. I quit smoking last September and I know that's responsible for some weight gain but not 46 pounds. I walk for half an hour every day, watch what I eat and do cardio arm and leg exercises. I also have a rash on my arm, which is says in from Plavix, and he took me off it. I had a heart attack last September. Anyone else experiencing these problems?

I quit Lipitor (40mg) five weeks ago. I believe I was on a trajectory to disabilty within a year.
The unbelievable left elbow pain has gone (maybe the cortisone worked!). My left knee feels "normal" again, not perfect but nearly like it used to be. Within a couple of days of quitting I had severe pain in my right thumb along the bone, then in the middle of my right hand, then between the first and second fingers in my right hand. I currently have minor pain in my right wrist (this is new) on the pinkie side and minor pain in my left shoulder where the arm joins (this has been intermittent for a couple of months). I am feeling much better - but would not be at all surprised if pain appears in another part of my body before this is all history! There is also plenty of joint clicking going on.
I believe I first reported pain to the assistant doctor to the heart surgeon two weeks after I had the stent put in and was put on Lipitor. I was also on various other medications. I had tingling on the ends of my fingers and toes at random - hard to describe but it was as if a fairly sharp object (like a ball point pen, say) was being pressed progressively harder from the end of the finger/toe and towards the rest of that finger/toe: and as the pressure increased it would suddenly become painful. It was not a tingling/numb sensation but more a tingling which increased sufficiently that it hurt.
I am only being so specific because when I described these "symptoms" the doctor shrugged. If anyone has had similar - and I have seen tingling mentioned here - please make contact with me as I do want to report my experience back into the medical community but find, an exact description difficult. Things never needed to have got so bad if this was the first warning.
I since asked my family doctor if my knee problem was Lipitor related and she thought not: I was referred to Physical Therapy. I also told the physical therapists (who thought my knee should recover much sooner, and were surprised that I had zero mobility pain) that I also had serious elbow pain.
The orthopedic surgeon I saw did not connect the elbow problem to Lipitor.
The heart surgeon (stent insert) could perhaps be the only person who I did not tell of the pains - I don't remember - but I may be so grateful to be alive - that he may be someone to whom I did not voice a complaint!
On the positive - five weeks later I am feeling significantly better.

I was given 20 mg of Prednisone for 10 days for a rash and joint pain.
The pain went away and I felt great the rash got a little better. Two days ago I took my last pill. I woke up that night and my knees gave out. By morning I was great! Next night I woke with knee problem again had to slide down the stairs to the living room. I got to wondering if the knee thing could be associated with the Prednisone. I got on line and read all this terrible stuff. I am so Horrified! Today I am in pain like my body is bruised and my face is swollen a little. I have acid reflux as well. Non of this is typical for me. My knee thing is ok again, but I am just appalled! I have no MED insurance. I hope this isn't the beginning of worse things I am not taking that drug now. The Dr. didn't say I needed to taper...

I hope I have not damaged myself by taking this drug! My heart goes out to all of you! My question is - Why are the Dr.'s prescribing this terrible drug?

I am 27 years old, male, and have had type 1 diabetes since I was 8.

My doctor prescribed Zocor repeatedly in 2007(for high blood pressure) and I was reluctant to taking it because I have no respect for any of the miracle drug companies and feel that they are only looking to make money, not help anyone with their health problems. I finally started taking Zocor (generic) in Nov 2007, then started getting some strange side effects that my doctor never mentioned when I asked him.

My side effects were, but not limited to, muscle pain in the legs and back. I noticed sharp pains in my knee like arthritis and Charlie horses in the calf during time at sleep. I noticed these after about 1 week of taking the drug and lasted through till the end. I stopped taking the drug in Dec 2007 and been off it since. I have yet to talk to my doctor about it, but I talked to his nurse and she recognized the symptoms. I reached my conclusion long before speaking to her however.

Now 2 months have passed since I stopped taking the drug and the pains in my back and legs have disappeared. The arthritis type feeling in the knee has gone away. I have more flexibility and none of the pain that I felt while taking the drug. I am astounded that the clinical trial for this drug doesn't note the muscle pain; at least the notes from trials I found on the internet didn't note it as a side effect.
