HI Kerry,
I agree with John that an anti-inflammatory diet helps. I'm a registered dietitian and eat a primarily organic whole foods, plant-based diet, high in anti-inflammatory foods and fiber. Don't forget about fiber--it is probably the most important neglected nutrient in the ultra-processed American diet. Fiber feeds our gut microbiome and our microbes help protect us from diseases-- https://newsinhealth.nih.gov/2012/11/your-microbes-you
As far as exercise goes, I do aquatic fitness, pilates, and dance 6 days a week and the only thing that has ever bothered me is using 5# hand weights versus lighter weights. My shoulders seemed to ache at night after using 5# weights. Not sure why, but my symptoms seemed more like PMR pain than after-exercise pain. I've been in remission for a couple of years now, but only had a mild case to begin with. Hope this helps you in some way.
Hugs,
Janice
