I collided knees with another student while sparring in Taekwondo back in November. After waiting about 3 months I finally went to a doctor because the pain got so bad and my whole leg was going numb. He prescribed me with an anti-inflammatory and diagnosed me with a deep bone bruise. (I got X-rays but those came back clean) It has now been about 6 months and I have been seeing a chiropractor for about two months who realigns my knee. (My tibia is going one way while my femur is going the other) If any could give me any information to what could be wrong I would be so grateful….
