Cardiac risk symptoms and conditions

I took Levaquin for recurring sinus infection - my doctor prescribed 3 different series. By the 3rd prescription I had developed severe joint pain, mild depression, rapid heart beat and chest pains. Blood tests showed that my cardiac risk factor was elevated. I have been off of the medication for over 6 weeks, I am taking nutritional and mineral supplements but still experiencing joint and tendon pain throughout my body. While I have exercised all of my life just walking is painful. My tendons 'pop' at odd times and are very painful. I also have nerve pain/spasms that randomly shoot through my joints.
