Had hit knee while snowmobiling. Have hard sensitive lump. Cure?
2 weeks ago I was snowmobiling and I hit my left leg about 4 inches below my knee . Hit going about 25 mph and it was very bruised and I could barney walk on it for the rest of the day. Now 2 weeks later the swelling and discoloration is gone but there is a very hard lump where I hit it and very sensitive to touch.
