i injured my knee kneeling down on my knees in my boat.I went to my family md and he gave me a round of anti biotics. My toenail became infected a few days prior to this injury and had seen my dr about that and mentioned the knee injury. well, the toenail shot infection out of the tip and later the nail raised up and came off. Now yesterday, i noticd a swelling about the size of a grapefruit above my hip bone on the back. There is no redness, only a bit of tenderness there. I am concered, but just wondered if these 3 incidents could some how be related??
