Hey

So iv been getting loading doses for B12 deficiency, my b12 was 105 improved to 124 after a month and a half of eating more meat than a cow has at doctors advice... I am being tested for coeliac and my thyroid is wonky but not getting retested till july. Unsure yet if b12 will be continued or is only a loading dose. initially he wanted me to do 4 x doses for 2 weeks but im self employed so compromised with 2 x a week.

I have Ankolysing spondalytis, a hip replacement Fybro like pains, EDS hyper mobility - so major immune crap really

medication wise all im really taking is Embrel by injection, Arcoxia when needed and my contraception pill. I cant take paracetamol etc right now it makes me nauseous.

So first loading dose i had a cold so assumed the symptoms on the next morning were related to that - flue like head stiffness overall weakness. the next day was fairly fine.

second dose felt sick almost 10 mins after the dose couldnt life my head up when curled on seat for hours couldnt be vertical etc.

Third dose symptoms returned so i knew it was b12 but yesterdays dose is horrendous, my arms are now like lead balloons like when u get a flu jag, both are red occasionally nippy but always aware of them, i feel sick constantly col fevery migraine and generally feelig pretty rough but trying to not waste two days as i feel like iv wasted 2 weeks.

Overall i dont feel any better, my hands still tingle feet tingle, random swelling reactions hair is breaking worse but unfortunately that could all be also the thyroid.

Has anyone ever experienced feeling like this with b12 injections. I have two doses left on loading but i cant take any time off after them. one is on tuesday im working 16 hour days wed and thursday. im expecting to feel even worse with each dose. im unsure if its my immune system playing havoc or im generally reacting to the actual b12. ITs Hydroxycobalamin im getting.

any general idea of how yoru meant to feel would be really appreciated thank you x

    No that is not a usual reaction. Your level is still low and it will take sometime to adapt and even longer for the neurological things to improve.

    In the first place consult your dr, as at the least he she can monitor you with tests or refer you to a specialist none of which we can do.

    You should not be working 16 hour days in your condition.
