I got the second shot in Feb and yesterday I got the booster Pfizer shot you know, everything was fine I went to bed last night. I woke up this morning and the site I got my shot on, which is my left side underneath or my neck, underneath my ear all the way to my shoulder cramps up and that's what woke me up. Once I get the cramp relieved I got to watch how I move before all cramp again its been cramping on and off all day. The only thing that seems to help is putting pressure on it from my hand on the left side, if I try to use my right hand it cramps and stuff like but if I because I am stretching too far I guess, but if I use my left hand I can almost stop it from cramping. My problem is I don't know what to do I have been using Icy-Hot (Intent treatment) but like I have got to get up here in few minutes and use the restroom. I know once I start walking it will cramp before I get to the bathroom in my house and then its I don't know its not really a cramp but it feels almost like a cramp only its very, very painful. So, its not a cramp its something that you can feel in my neck how it tightens up and I don't know, is that a side effect?"
