Prone position symptoms and conditions

Eight years ago I started with 10 mg. Lipitor and took it without problems for about five years. Doctor wanted me to change to Crestor and within four months I could hardly walk, shuffled my feet and had pain in muscles. Switched back to Lipitor two years ago and this week began to experience muscle pain so I stopped taking it three days ago. Any time I am in a prone position, or sitting, the leg pain is incredible. Walking there is minimal discomfort. Tried a massage today to no avail. Any way to alleviate this withdrawal reaction, if not, when might it dissipate?

I just started using Singulair a few days ago. I am 54 years old and just started coughing at night only. I would be fine during the day and then never failed, at night I started to cough keeping me awake. I was given antibiotics, narcotic cough syrups but it only helped temporarily and then I went back to coughing nights only again. So as I mentioned, I started taking Singulair a few days ago because my physician thinks I have developed allergies and Singulair is noted to help night coughs. It is helping my night coughs but I still cough a few times at night and now I cough quite a few times in the day when I never use to cough in the daytime. Wondering if Singulair is worth taking as the symptoms are becoming opposite? I hate taking drugs and don't know if I should find a safer alternative? Help, anyone? Thank you
