aww thanks i hope he is able to walk soon ,he is such a crab. i hope you can get help for your knees. but you could have an infection throughout your knees possibly from not being treated. this is just a guess
My dad broke his pelvis when he crashed into a dog on a bicycle..
It took him about 3 months to be able to walk without crutches( I think) and he did physical therapy exercises all the time(which I think sped up the strengthening process)
It took him much longer to walk without a weird limp but he was mobile by then.
Best of luck to you and your boyfriend
