Thank you John for your kind and thorough reply. Sorry for the biological reference, I studied marine biology and was Intregued that “sea” within an ocean is a little understood place in the Atlantic. As far as my symptoms, I’m keeping a sharp eye on the GCA stuff, as I know this is very serious. I did have jaw stiffness, plain, temple pain, scalp pain and immediately contacted MD and she upped by meds back to the 15. Pain subsided within a few days. The muscle cramping in weird places still plague me, and never know when it will hit. I just wish there were other “treatments” instead of steroids, but I dont’ want methotrexate.... I’ll check out your post and keep up on what others are sharing. I’m feeling like this was triggered by getting the Shingrix vaccine. Btw, I am not an antivax person. Trained in bilology, married to a research scientist, I trust science. But with that said, the symptoms came on quickly after the second vaccine... thanks again John.
