I have developed the syndrome part since I had my son. I also have thyroid issues and basically anything that weakens my muscles impacts (which thyroid does, and low vit d etc.)
So yes basically being strong etc.
Good pain relief and management for flares.
A good bed.
They say don't jog etc but I find I can and it helps, I also swim and skip and used to do martial arts. I've started pilates - I find its helped me to learn to stretch my spine which has stiffened up, due to over flexible arms and hips. But I really like Forrest yoga - usually with jhs this is a no no but my teacher knows my issues etc and it has a lot of core strengthening stuff.
Massages, a good sports physio (who has recommended some of the yoga twisting stretches)
Epsom salt baths are awesome. And I take extra magnesium and calcium and vit d now.
A vibrating massage thingy.
Thinking of trying tens machine for flares.
My residual issue is that my hips shift and cause lots of spasming and tightening. Sitting and travelling is tough.
I really should be doing my physio much more often,
