2 weeks ago I was sitting at my desk and noticed a little soreness on my inner thigh when I turned in my chair. I touched it to see if it was a bruise and felt a knot/lump. I went to the restroom to see what it was and noticed a little bruising. None of this had been there two hours earlier. Within three hours of noticing the knot and bruise they both had trippled in size. I chose to go to the ER and was told it was a busted blood vessel. After two weeks the brusing is starting to clear a little but the knot is still the same size. About the size of large gumball and still sore. The bruising area is larger than my hand but knot sore. I am a 32 year old female with no health problems and there was no kind of accident to cause this. Is it normal and how long should it take to completely heal (knot and bruise)?
