I would assume that the MRI should have been the first step...Make certain there is not something there before someone starts doing manipulations, etc...I, personally, would have started with a good OSS...let him make an assessment...He would probably send you for an MRI...make an assessment from that...then determine if a shot is necessary...then maybe some aqua therapy...or PT...stay away from the Chiro...just my opinion of course...maybe Yoga...AFTER you see the OSS of course and get permission...get an assessment first...then proceed! I agree with Kathi...100%...Good advice! The epidurals never worked for me...SI joint injections did, but not epidurals...They are two different things though!
