So sorry to hear about your woes, @BigButtons! That sounds really tough. I'm afraid I've joined the Walking Wounded Club as well - intermittent pain on my side, just above my right hip, golfer's elbow and a painful left shoulder. Even though I do warm up religiously and do lots of stretching.
I think I've just been overdoing it, especially using heavier weights than I should. I think there is a risk one ends up doing this with Iron, so I'll go back to Heat or Endgame once I've recovered.
In the meantime I'll stick to stretching and my old favourites. Lots of planks as well. I hope you recover soon,@BigButtons🙏
