I was suffering from pre patellar Knee Bursitis from past exact two months. Swelling and inflammation is no more. But can't give strain to my right knee like standing straight with the same knee and still I can't walk normal. I can but like tortoise. I am doing my exercises regularly as suggested by doctors but still I feel that jerk inside and outside little pain. One thing it has been reduced to 70%. Does it more time to heal completely?
