Do research symptoms and conditions

My husband was diagnosed with MS 2 1/2 years ago. He has been on Lipitor for about 1 year. Within the past 4 months, his walking has gotten worse. Where it used to be just his right leg, now it is his left as well. Severe leg cramps, fatigue -which could be the MS - trouble keeping balance - also could be MS - lower back aches, slurred speach and memory loss. I know alot of these are associated with MS but after reading all the other letters, I am beginning to wonder if his walking has gotten worse due to the Lipitor. He used to have trouble walking but with a cane, could go for miles. Now he can't even walk 15 minutes without almost falling. A friend of ours stopped taking the Lipitor and felt better within 1 week. I am hoping the same happens to my husband. Thanks to everyone for sharing their stories.
