I have a posterior twisted pelvis- the right side of my pelvis is rotated backwards most likely due to all of the muscles on the right side of my body to be super tight. (I am also left handed and most of the muscles on the left side of my body are stronger).It started after I hurt my back telemark skiing about 6 months ago. I’ve tried chiropractic and it didn't seem to help, and my physio has got me stretching for 30 minutes every day s for the past 4 months focusing on muscle imbalances with no improvement. Most of the pain is in the lower back around the SI joint but also radiates into my left glute occasionally- and my left glute is super tender. I've also tried IMS and acupuncture and am thinking about trying massage (ART?). I have also been focusing on activating and strengthening my transverse abdominus and multifidus muscles in my core and back. I am a competitive Nordic ski racer and even though the pain isn't that bad it has limited my training and I need to get it better a.s.a.p.
What do you think is the best treatment?
