COVID and vaccines work by increasing the cytokine/bradykine level in your blood. It's how it creates immunity. How many of us have immune deficiency but taking flour and covid and other vaccines at once. Never take more than one vaccine at a time. Our bodies are struggling just to function in the face of other immune disorders never mind taxing it to where it won't fit any antibodies. Getting the shot doesn't guarantee antibodies. Drs say it's ok to take several vaccines at once. My cardiologist who is treating 12+ children a day with cardiac issues post covid, says at least a month between. Makes totally sense.

So ask to have your flammatory markers checked. Many of us with preexisting immune disorders are already living with adrenal Fatique. Where do you think the vaccines hit? It's a whole big messy system of checks and balances in our adrenal gland.

Many with covid are also finding an elevated histamine level which is known to cause itching and esp if an "anti-" histamine helps. There are histamine disorders that can be triggered. Best of luck.

And many of these things will fall under long haulers. I have lived with longhaulers- now on oxygen and looking at buying a wheelchair...for 2.5 years. I also have CRPS which is much worse after my second dose of covid. Nearly bed ridden for 5 weeks now.
