Hello, I have been taking Lovastatin for a couple of years and recently I ve started to have a lot of joint pain, backaches (very severe), my knees hurt, etc. Is it possible that the Lovastatin is causing this? I also take Metoprolol, Torsemide, Entresto, Warfarin, and Potassium. I have CHF and AVMs in my lungs due to complications from Tetrology of Fallot. I m 56.
