I have ongoing SI joint issues and am back in PT for it. This time I think getting hit by a ski lift chair because the lift op didn't hold it set everything off. Anyway, 2 of my symptoms are painful sitting and low back pain. Stretching doesn't help at all and Pilates made me more painful. I haven't tried Pilates since my SI Joint issues were discovered although my current PT thinks it's probably ok. The last PT worked with me in getting more mobility in my spine due to a flat back. Now when I exercise my left glute gets very sore and painful. My current PT, and I agree, thinks I have an asymmetry in my hips. Yesterday, he had me doing RNT squats with a band. The way the are performed works individual hips. Yikes! my left side felt strong, confident and also reacted with some muscles soreness. The right side felt like a wet noodle and fatigued very quickly. My left side was still complaining when I got home. I know this sounds dumb, and to remember what I did, I repeated the exercises again on the right. The left side calmed down.
My point is you have to keep searching for answers. My last PT promised that getting more mobility in my spine would solve my problems. A year and half later spinal mobility created more problems and I'm having to continue my journey toward performing my activities without pain. I refuse to accept that being 65 causes my pain. Inappropriate posture, long time SI joint dysfunction, stressing it with activities that I didn't train appropriately for, in other words just living a full, active life contributed more to the issues than age does. As I read certain authors and learn about my body I'm accepting that this is a continuing journey that I will deal with as I age. I see my friends slowing down, stop living their passions, if they were passions, while I continue to learn, grow and thrive at my age. I have a friend who is 75, skis like a 30 year old, biked cross country at age 73, she was a newbie cyclist, and this year climbed Mt Kilajamaro. Who knows where her passions will lead her next and I plan to be just like her in 10 yrs in spite of my SI joint issues. Sorry for my rant but I know too many people, often younger than me, who give up their activities because of pain, back, knee, etc. and blame it on age.
