Doctor.. I had chest congestion about two weeks back and I was given Pencillin injection and Antibiotic Redclox for 5 days and I got relieved. While the symptom of congestion started, I had severe body pain and I had lot of pain while bending my leg and hand fingers. After the treatment it was alright. Again last week I got some pain in the leg and I am given Hifenac MR. If I stop taking the medicine, my left foot there is severe pain and able to put pressure. Other foot and hands are alright. I took xray of left leg and the doctor said it is ok, and only muscle pain. But once the medicine is taken, I dont get any pain for one day , and after one day the pain comes severe. Please suggest.
