Hi Karen, thanks for asking me to clarify 
- I actually mean debilitating side effects from & since my jab, i.e. my first Pfizer vaccine, that I have been describing in detail here on my blog. It has probably caused a histamine condition, so I’m treating it like mast cell activation syndrome, which I think it may be and am having some success doing so (with supps & a bit diet).
As to your stabbing pains - I do get them occasionally, like in my thigh the other day trying my wife’s weighted blanket for an hour (and afterwards twitching for 1-2 minutes) . So I get what you mean, they can feel very much like knife jabs and hurt much more than needle pricks. Now I’m curious: Have you an idea what is causing and what to do about them?
Whilst some I spose are muscular, like the one I got from the weighted blanket others I think may be nerves, so I’d be trying magnesium malate or magnesium glycinate and various exercises, something like a TENS unit, as well as acupressure for both. Have you tried anything for it?
