Ever since I was like 12, I've had a problem where it sounds like there's a small bubble underneath my knee cap and it pops, it's followed by excruciating pain. Sometimes it's not that bad and I don't feel anything but when it hurts I have trouble walking for a few days. It doesn't swell and I used to do sport like track and lap swimming. I was wondering if anyone else with hypermobility has this problem or if I should ask my doctor about it? I've always had trouble going to doctors about these things because of a bad track record with them.
