I've been having pain stemming from my Sacroiliac joint for years. I first went to a chiropractor in 2009 because my lower back was constantly feeling like it needed to "crack" but wouldn't. I'd been having pain in my right gluts and none in the left but when he barely touched my left side I yelped in pain. He's the first one to tell me he thought it was my sacroiliac joint causing me problems. He explained how the muscles on the right side were contracting, causing the pain, and pulling the left side out of alignment. Through some stretches he taught me, a couple of a adjustments, and continuous yoga I was able to "recover." Then a few weeks ago I started having pain again but it wasn't just my lower back this time. Things were complicated by the fact that I play several instruments that put a strain on my upper back (flute, guitar, mandolin) and was having pain there too. I went to a massage therapist who was able to relieve the muscles in the upper back but when she touched my lower left side I again yelped in pain even though I'd had no pain there before. She said she thought the SI joint was the problem again.
I decided to go to the doctor and get some xrays, just in case. The xrays show I have mild Scoliosis. The irony is I was checked for this as a kid. The school nurse sent a referral home because she thought I needed further examination for scoliosis from a doctor. The doctor said I didn't have it, that I must have been standing crooked during the exam and that's the last I heard of it until now, 28 years later.
My question is, is the SI joint pain caused by the scoliosis or are they 2 unrelated problems?
