My flare came after a flu and a Covid shot (2 weeks apart). Could be that. But then again, I had a colonoscopy in that time period too. I’m a healthy critter all in all but I believe that was felt as an onslaught to my immune system. Too much in too short a time. Plus I was overworking myself, stressed and tired. Now I’m a year older and my arthritis is kicking in! I tell ya. We’re lucky, though. We’re alive. We have access to medicine that brings immediate relief. We don’t have a fatal disease to contend with. And I don’t know about you but I am mobile. I’m counting my blessings. PS Sorry you’ve been through the wringer! Heck of a thing.
