Today after putting ice on my knee after my lunch walk (not running since the knee pain has been so bad lately) I started thinking about why my knees hurt so much lately. I haven’t really been running that much but my knee pain is much worse than usual. A quick google search for Crestor and joint pain and I found out that joint pain can be a side effect of taking crestor. I take crestor to lower my cholesterol (which it is doing pretty well). I scheduled an appointment with my doctor to talk about it and see if I can go on something else for my cholesterol or just stop it for a month or two to see if the knee pain improves.
