Hey this same type event lead me to this site and ultimately my Lyme daignosis.
In one of my numerous Specialist visits, my D tested at 15. They gave my 50k D2 dose weekly. Knocked me flat on my back for 2 days. By Monday I would feel Ok. Tried smaller D3 5k dose and the same.
So I googled " feeling worse with vitiman D" and somehow got to this site. I read somewhere in this forum that Lyme does not always react well to VD supplements due to you actually having too high of level to begin with. Has something to due with the usable level. I,m going to ask my doc to test my D 1,25 level.
If it's Herxing,, we'll ok I'll go slow but this is one rough herx if that's the case.
I want to be sure I,m not posioning myself by mistake.
