I'm a 31 year old Type 1 diabetic female. I have had diabetes for 25 years and have extremely good control of it...I have not had any complications. I also have never had any problems with my knees. Back in May, I bought an exercise bike. I used to run but, when I moved, decided that a bike would be better. One night (after only having the bike about two weeks) I really went to town on resistance and how fast I was going. My knees felt fine but the next day, after driving for two hours, they gave out.
I was able to walk, but my knees felt really wobbly. There was no pain whatsoever. I finally gave in and went to the doctor. He had an MRI done on one knee (the left, which was giving me the worst trouble) but there was not any sign of injury. The doctor recommended taking Aleve and letting the knees heal up on their own. After a few months of very limited improvement, I ended up going to a knee specialist. My knees were extremely tight, I had lost my ability to kneel down or even squat down, and my ankles were swollen. He also could not find sign of injury, and x rays and tests didn't show injuries or signs of arthritis. His diagnosis was that I had sprained my knees because I was not used to my bike, and that the hamstring had tightened up. He ordered PT, which began in October.
I have seen serious improvement in my knees after I began PT. I went from walking like a weeble wobble to walking like my old self. The ankle swelling is all gone, too. The only thing that seems to be bothering me still is my knee flexion. It's still very hard to squat down, as is kneeling. I used to be able to kick my heel to where it kicked my butt cheek, but now the heel is about four inches away from the cheek. This is improving, but very slowy. Also, sometimes the muscle behind my knees hurt.
Is this something that's normal? Does it normally take this long for a knee injury to go away? I've always heard that the knee is one of the worst things to injure, but this is nuts!!
