I have a mild pain in my right knee exactly where the joint is. It only hurts when I jog, run, walk up/down steps or kneeldown, I can straighten it fine, although there is a lot of clicking (not just one big click, but rather 2-4 small clicks). There is also a very audible crunching/grinding sound, like wet sand or stone.

The knee is not swollen, its not sore to the touch, doesn't hurt when I put preasure on it, the pain is only felt during bending or straightening (when weight is on it).

I don't know what could have caused this, but I've had it now for 7 months and it's really starting to affect me. The only thing that I can think of is from running, I used to do it a lot 7 months ago.

I thank you for any advice you can offer me.

Have you seen a doctor about this? If not, it's time to make an appointment.

That's what I had before the MRI showed is was a tear in my meniscus. See a doctor.
