what to do.....
I recently replied to another thread here about reactions to B12 as I'd also had a very severe one, resulting in a seizure, persistent cramping and chest pain. I couldn't even walk properly. My GP said I was the 1st person to report such a reaction and has ceased all my B12 injections for now until he can find out what went wrong.
On the other thread (I wish I could find it), someone answered that such reactions are known to occur with potassium deficiciency, and posted a link. Having read it, I'm convinced that is what may be happening with us. Apparently in a person with severe B12 depletion, the B12 injection causes a sudden drop in potassium levels and that results in the frightening symptoms.
i hav bin having same after my first injection wiv b12 but i was thinkin its just another flare up wiv my lupus but i am feeling better now but its awful when u feel like tht i end up crying coz i felt tht bad i was white in face nearly sick n pains everywhere n felt so tired
thank you all for your replies since putting on post i got severely worse which resulted in me in a great deal of pain and finding it very difficult to walk, bad diarrohea and also blood in my urine sample so my kidneys were also struggling.... and feeling very ill and scared as to what was happening to me .i saw my doctor on one of the worse days and said no more injections and was referring me to a specialist.....even now 5 days later i am still poorly...
but reading your replies have helped as dr made me feel a freak......
and when i see doctor again i will mention the potassium.......thank you all again
What to do?
What do I do now?!
Lightheaded
Confused is it B12 deficiency or not?
New here and needing help and encouragement
