I have not had it diagnosed properly, but i do feel the weakness there myself. bottom of the spine right hand side close to the bottom spine.
i have been to a cranial osteopath who said she could feel the weakness in the SI joint.
A few years ago, a chiropractor xrayed my spine, and down the bottom right hand side was a bigger bone than the other side, he didn't properly explain it, so i can't explain it here.
constantly feel muscular tension in the lumbar area of the spine, muscles seem tight, i do a lot of yoga and stretching to help it.
i take anti flammotary tablets 3 times a day, doc recommended i take them. been to see nhs physios, who give me little exercises to do.
i find that standing for a long time is agony.
not sure what treatments there are for SI joint inflammation.
I do feel i am not in so much pain as some of the members here.
