question: Dear Doctor, while I was driving my scooter at night, had a fall from scooter due to a big pot hole filled with water, and fell on right side, was dragged a few metres, skin just below knee had deep abrasion, but appeared like no damage was done to bones. Even after 3 months, the wound on knee is not completely healed, shows swelling like mass of skin at the centre of wound below the knee. Also, I am not able to bend the leg fully , not able to squat (while going to Indian type toilet). but have no problem in walking or running. I have undergone physiotheraphy, I also got MRI scan done, which indicates thinning of anterior miniscus. Kindly advice me whether this can be cured by medicines or external application of oils
