About 2 and a half weeks ago, I was diagnosed with cellulitis of the knee and was given 2 shots of antibiotic and prescribed two weeks of antibiotics. During that 2 weeks the infection had spread down my leg and into my ankle and foot, so my leg from my knee down was swollen (huge), and red all over and burned really bad. It was very painful and couldn't even barely touch it without pain to worsen. The infection got really bad. Now after I'm done taking my antibiotics, my knee and leg is a lot better, but still has some internal swelling and I don't have full movement back in my knee. I can't bend it much, nor straighten it all the way and is still very tender inside just to use and outside to touch. The swelling on the outside appears to be mostly gone, except a few spots on my knee itself. I have also got a spot on my knee cap that is very hard and tender and looks to appear red, and or the look of a bruise. This is the spot it originated to start, before it spread. Can anyone tell me why I have a hard lump like spot on my knee like this after, if its normal, and if this will go away, or if it's something that might need taken care of? There's still some present issues from the infection and not sure if I need to be taking more antibiotics until its totally gone, or if it will just continuely get better from here. I've been worried its something going on wrong with the bursa that my doctor said was wanted to avoid. Can anyone give me any answers or advice? Much appreciated!
