SI Joint Muscular Strengthening

[Mav]

Gents,

I thank you in advance for any advice!

When I was AD, I injured my tailbone on a jump. 3rd Degree Sprain of the SI joint area. Bunch of nerve damage, etc, from there down my left leg (point of impact was JJUUSSTT slightly left of midline).

I was lifting something, yesterday, and while it was somewhat heavy, I didn't feel strained. Quite suddenly,I felt a very painful jab in the "impact area" and my back locked up; I couldn't straighten up for a good five minutes or so.

I work with computers and a lot of my job requires lifting towers, etc, so I need to try to support that area. Does anyone have recommendations on some self-imposed Physical Therapy that I might do to help resolve the issue? Hoping that it isn't purely nerve-related (which some of it is).

Thank you!
