I had medication changed due to my arthritis and pain. I have not taken the Crestor in the last 2 weeks. I am having increased pain in my knees and shoulders, I am unable to sleep and I feel tired. I have been to the Dr. 3 times in two weeks. He is trying to resolve my other issues. I remembered I did not tell him that I had not been taking the Crestor. I have not been feeling like myself in 3 weeks.
