OK. You said "leg curls," so that is a little confusing, too. There are two single joint knee exercises, leg extensions and knee curls. Knee curls are the ones where you lie on your stomach with the padded bar on your calf or achilles, which you curl toward your butt. Knee extensions are the ones where you sit with the padded bar on your shin and straighten your leg. I wouldn't do either one.
Most docs don't know squat about it. I had knee pain one time - went to an orthopedist who told me: sorry, you just have malformed knee caps and legs, better never exercise and just get used to a life with pain. That was uh, 10 hard cycling years ago. Another doc told me that with the tendinitis in my forearms - just sign here; I can get you on disability and you'll never have to work again. (:-)>
I'm no doctor, so I don't know much physiology, but there are three things going on behind the knee. There are the two major tendons, one each on the inside and outside of the joint. When you flex your ham with the knee bent 90° they really stick out. Then there is a large muscular pad between them that sort of joins the ham to the calf muscle. Is it one of those and if so which is it?
Sounds to me like you might just have a little tendinitis. Easy spinning and Ibuprofen. Let it rest.
