It's a crazy journey. And literally, I feel your pain. A while after my first Moderna booster in late 2021, I started with back and shoulder pain. In early January 2022, my symptoms were crippling. Had little use of my arms, no strength and aches all over. It took months for a medical professional to finally converge on a PMR diagnosis. Finally weened off pretisone by year end. Then jumped into physical therapy to regain range of motion and strength. Slow journey. Still at it. Much progress though. Grateful for that. I appreciate now being connected to this group. Take care.
