hi there, so I was recently diagnosed as being deficient in b12. I do not test positive for intrinsic factor but for parietal cell antibody. I had a number of neurological symptoms that came on at once a few months ago-the main symptom being a burning scalp, then on/off dizziness and an on/off feeling of not being connected to the environment. I received loading doses of 5 injections in 10 days 1 month ago. the dizziness amplified during this time of getting the injections and just started to fade off when I got my first monthly injection yesterday (the neurologist recommended the loading dose, then 1 injection monthly for 6 months and then 3 monthly). also after the loading dose I got pins and needles in my limbs, particularly my left arm and hand. this is on/off but a symptom I never had before. I have had no alleviation in my scalp burning. it is usually more prominent in evening but can be on/off throughout the day.
I am just wondering is it normal to have adverse reactions to the shots? is the pins and needles my nerves re awakening? is the scalp burning related?
I am getting hydroxocobalamin. all other blood results are normal. hormones all normal except very high levels of cortisol. ive been referred to endo to investigate same.
all help would be appreciated
