Thanks for your input! How do I go about doing that? - how to investigate, what the treatment would be, etc. I've been putting ice on it during the day and it doesn't seem to be helping. I thought maybe the initial numbing agent did something but it wore off quickly. Walking and standing is brutal but luckily I can sit for work purposes, which wasn't always the case.

I did chiro at one point consistently with proper alignment and still had issues...

It's amazingly difficult to get a proper diagnosis of the cause of the pain and then how to treat it.
