I am like you in that I used to keep up with friends and social activities. My husband and I used to go to national parks and do small hikes. I loved it and miss it. It's weird that mine comes and goes and moves to different areas. My Gluteal Tendinopathy diagnosis came after 2 years of thinking it was just bursitis. Collagen depletion in tendons is real and what can be done. Softwave or Shockwave seems to stimulate and regenerate the cells in the areas you need help. I notice my upper outside glutes will all of a sudden just pull and spasm when doing light yardwork or housework. It will pull all along lower back and spasm so bad on just certain movements, I have to stay in bed with ice and heat and NSAIDs. It takes a good week of resting and slow movements to feel better. It stays tender for a long time. I had also just started up my Repatha again, so now I wonder if it was that. I also found out my adrenals are fatigued and does that have issues with muscles. My Ferritin was borderline low. Would taking Estrogen help? So many questions and no answers. I was doing the main glute loading exercises like Bridge, adductor leg lifts, sitting clamshells (not laying on side). I found a Facebook group under Gluteal Tendonopathy groups with a Physical Therapist as the moderator that listens to our issues. I do feel building glutes back up helps and maybe doing Softwave. Some collagen support is recommended but I am on the fence on those.
