I received my Pfizer Vaccine in March, 2021 and I have received most of the boosters since then. I was diagnosed with fibromyalgia over a decade ago, but I was able to manage my symptoms and often had the energy to go on long hikes and play pickleball for hours. A few months after the vaccine, I started going down hill. By fall, I was gasping for air when I did anything with sudden movements, but I could still go on long walks. It continued to get worse. Unlike fibro, I only had short durations when I got a little better. Overall, my ability to do things has continued to decline. I got Covid in spring of 2023. By June, my ability to even walk short distances started rapidly declining, and other symptoms cropped up. I got a Covid booster in the fall, and I think I went down hill even more after that. I can't even walk around the block now without holding on to my husband for support. I think my muscles are failing me and quickly run out of energy, but that could be my brain rationalizing. My doctors are at Mayo Clinic, but I feel like I'm alone with this. (I do not tolerate most medications or supplements.)
