... to be taken 1 a day, for Bacterial Pneumonia. After a couple of days my calf, ankle, & foot swelled up and the tendon in the heel was real painful. That was over a month ago. The swelling has gone down a lot but is still slightly swollen and the pain in the heel area is still there. I am 75 yrs "young" and due to COPD I exercise twice a week on the treadmill & stepper. Will the swelling & pain ever clear up or is this a permanent situation?
