I believe I developed mast cell syndrome from vax-shedding + Covid. My arms were covered in a weeping red raised rash for 5 months. Doctors baffled and all they could do is offer steroid shots. It got so difficult to eat anything that I stopped for the most part. That’s until I studied more and found out there’s compounds in meat that can heal the condition. Also not eating only made it worse as histamine levels would rise.
