Help diagnose my knee pain .

Hi and thanks for the response. I don’t recall anything that would have precipitated the pain. If I recall, it just began during a run a few days ago. It subsided afterwards, but flared up again during a couple subsequent runs, more intense this time, and has stayed with me - walking down stairs is VERY painful, and just walking is uncomfortable unless I keep my leg virtually straight.

It is a sharp pain, but dull at times as well. I have tried to do a lot of stretching the last few days, but no real help there. Unfortunately, I am not sure what/where my lateral epicondyle is.

As an aside, I would be interested to know what you did to strengthen your pelvic girdlee muscles, as well.

thanks again for your help
