Was just wondering since I've been self injecting every 4 weeks down from 12 I've noticed different parts of my body going warm like I've got a heat pads on different parts of my body.was wondering is this part of the nerve mending process.
Also my tummy is more upset than usual.
Any one else have similar symtoms cheers
Sounds like your nerves waking up. Sinetimez it can be painful. K aksi still get a sudden sweat. (Not a hot flush) it's different .
Injections can causes diarrhoea at times. Or it could just be ttasit quicker through your metabolism speeding up. I o itislly altough mostly bedbound lost nearly a stone in weight and was so hungry! It settles though.
Yes I got warmth in my fingers and toes and tingling as the B12 went into my system. Also had upset stomach, it felt acidic, but actually the best for me was to take acidic foods - I ate a raw coleslaw with just lemon juice on. I can't remember where but there's something about B12 deficiency causing acid reflux symptoms but it being cos acid is too low....Like you I think the warmth is the nerve mending - fingers crossed
How often you inject ? Do you take folic acid ?
I was every 3 months...but was not enough.symtoms where getting worse doctors won't budge from every 8 weeks so bought my own as well so do every 4 weeks .
I take one folic acid tablet once a week with multi vitamins
Self diagnosed due to taking oral supplements so GP not interested! Self injecting every other day/once a day/ every 36 hours for 6 weeks so early days still for me. I took 20k mcg orally for one month prior to injections. I take a range of supplements including folic acid, Vit D, K etc.
I get the warmth but think that’s my thyroid xx
seeing neurologist, advice on b12 injections welcomed…
Serum ferritin too high?
