sinusitis
"Prescribed this medicine for a recurring sinus infection.  Doctor at N.W. allergy said you may have some tenderness in your lower leg tendons near ankles just don't exercise while taking.  After a week in a half of taking medicine I could barely walk. Kept taking medicine because pain was in my upper calfs and knee joint.  Then it went into my shoulder. The doctor insisted it wasn't the levoflaxin. Two weeks after finishing the medicine I feel like an 80 year old women with bad arthritis,  and prior to this I was a healthy active 51 year old women. Doctor still insist it wasn't the antibiotic I just woke up one morning with knee and shoulder joint and muscle pain for no reason.  This medicine is not worth the risk and can change your life."
