I know how you feel,,,, I was bruised by a baseball 6 years ago on the inside of my calf muscle. I had it then, Dr said that it came in from athlete's foot sore, and the infection settled in the bruised area from the baseball. I took antibiotics and it cleared up. I had it again in the other leg, again from a baseball bruise(i was hit in the leg with a baseball) this time It started to clot. I don't know if clots act the same for eveyone,, but my infected area that was red started to move up my leg to the bend of my knee,, the Dr made me keep leg elevated,, take tylenol,,, and alternate a heat pad and an ice pack every 20 or 30 minutes several times a day. That was for the clot. Antibiotics for the infection.I am not diabetic now,,,, that i know of,,,but diabetes runs in my family. I am a 25 year old male. Hope my story will help and any other advice from others is welcomed.
