it's been months that I don't feel well and i'm really worried about my health. I'm gonna describe my story so you can maybe help me with this.
First of all, I'm 27M, vegan for about 3 years now, while before I used to eat meat almost everyday. Anyway, since i'm vegan, I was used to take solgar multivitamin formula vm-75 often but not consistently.
My sysmptoms started about a year ago, during christams period. There, I started to feel weak, tired, and to have hypersalivation and heart palpitations. I thought that those symptoms were due to anxiety and stress from University and so I didn't go to my gp until the beginning of february.
February was really a though month because I was feeling very very tired, dizzy, light headed, breathless, and I had palpitations and numbness on my fingers. The doctor visited me and I took a blood test to see if I had some problems with my thyroid, an infection, anemia, or a vitamin deficiency. And from the test I found out I had a sever vitamin D deficiency.. while my b12 level was about 500/600.. i don't remember right now honestly but it was around those values. However, during that period I was taking a multivitamin and I didn't think to tell it to my gp, since I didn't know that the test could have been changed by it.
Anyway, a few months later I started to feel a bit better. The palpitations disappeared almost completely, and I felt a bit more energetic, less tired, and less brain fogged. But my symptoms were and are still present. Meanwhile, I kept taking a multivitamin as well until the end of july. Also, since I read that b12 is an energy-boost and it's impossible to go in overdose of it, I took high doses of this vitamin sublingually during june and july. In august, instead, I did not take any supplements.
At the end of august I took another blood test to see if everything was ok, since my symptoms were still present. And from it, nothing particular appear, I was not anemic, my vit D level was great and my potassium was okish (3.69 in range: 3.5 - 5.1).
My b-12 was, instead, 377pg/mL, and folic acid was 8.4ng/mL. So they were still in range, but I don't think they were great, especially because I was taking high doses of b12, and so, I was expecting higher level.
So, form the beginning of september, I started to take high doses of b12, togehter with folic acid, in every possible form: sublingually, through patches, and through stomach.. and I felt like they were helping me with my symptoms, but they are still here.. Some are better (i feel less confused) and some are new.
However, right now, I still have several symptoms. Like brain fog, dizziness, lightheadedness, derealization, muscle twiches, feeling of unbalance, tiredness, a weird feeling on my left thumb (if it's in certain positions, or after an effort, like opening a bottle, the thumb feels weird until it automatically returns to a resting position.. really weird), light palpitations, slightly low blood pressure, and weird sensation in my stomach (I forgot to say that during february, march and april I had a stomach inflammation, maybe due to my anxiety, in my gp's opinion..).
I'm honestly very scared and anxious because it's a nightmare and I'm not sure if it's b12 or something else, and i'm scared of the potential permanent nerve damage.
What do you think? Should I stop taking b12 supplements, wait for a few months, and then retake a blood test? How can I be sure if it's b12 deficiency or not? i read that injections are the best option in case of deficiency.. Should I give it a try, inject myself a few times and see if that helps me? Or do you think it's something else?
Thanks in advance for your replies.. Hope to find a solution or an answer here because my gp doesn't understand my situation and I don't know what to do..
