Ask your chiro what he thinks of the accuracy of the test. I don't know what to make of it.
The way I interpret it is if you press on the piriformis muscle as instructed and that doesn't cause pain in the leg, then you have an inflamed piriformis not PS. And your sciatica is caused by something else.
In PS, it is usually muscle spasm or scar tissue that causes the pressure on the nerve, not an inflamed muscle. The muscle can get inflamed from overuse like running or from the stress of an unbalanced pelvis that may result as a reaction to a disk problem or fall. That's my guess, anyway. Remember, I'm not a doctor or PT.
How has your ART doctor explained your condition, what needs to be done & how long will
it take? ?Three ART sessions is a bit early to expect improvement. But if you feel your not getting any effect, then it may not be the right thing for you.
I reread your first post. You said the pain started with the tailbone then moved to the butt. For someone who has not fallen, that is a very unusual symptom. It makes me wonder it something else is the cause of the problem & the piirformis is a response to that problem.
Has anyone every mentioned a possible problem w/ the ischial tuberosity? Theoretically, you could have developed "Weaver's Butt" from leaning forward while kayaking.
I really don't know what is going
on with you. I do know Dr. Filler will occasionally will find scar tissue at the ischial tuberosity & the pirirformis.
Please let us know what happens with ART & if you go on to Dr. Filler. Thanks, Good luck, Mary
