Hi all,
Before I get into my current state, I'd like to give you a bit of a backstory. Sorry for the length, but hopefully it'll give you an idea of how horrible b12 deficiency has affected my life and maybe there's someone out there with a similar story.
I've been initially diagnosed as b12 and iron deficient in Jan/Feb 2016 (but wasn't diagnosed as anemic) and was put on weekly iron infusions and B-12 injections for about 5 weeks. I started to feel much better and I've been able to keep my iron levels in the normal range overtime, but my b12 has continued to drop. About a year later, I started having all types of awful, severe symptoms, such as electric body shocks, pains up and down my left arm, pins & needles in the feet, buzzing/vibration sensations on the bottom of my right foot, headaches in different spots, weird headaches that felt like a burning sensation or as if blood was swishing around in my head, or as if my brain was being fried (hard to explain), brain fog, muscle/nerve spasms in head and other parts of my body, lightheaded/dizziness (sometimes felt like I was walking like a crab when moving forward), tinnitus, slight pain behind the eye, off-kiltered and unbalanced, anxiety attacks, etc.
One day at work, I was at wits end. I was walking to pick up food for lunch and I felt like I was going to faint. I called my doc's office and begged for an injection, to which then I was recommended to go to the on-site urgent care first and then get a blood test after before they were allowed to put in the b12 order. So I went to urgent care, EKG and everything was fine, but my b12 was a low 57 (normal range is 193-986 where I live). They sent me upstairs to my doc's office, got my shot, and was put on monthly injections.
I've felt so much better after each injection, but about 3 weeks after I start feeling the symptoms again, especially the weird stuff in my head (like something living up there lol), brain fog, spasms, dizziness, headaches. One time I scheduled a shot about 4 days before the month was up and the nurse was about to give it to me, but my doc stopped her and told her I'll have to wait til next week. (Mind you I was feeling awful at this point, but bit the bullet and waited a week).
It's been about a year since I started the monthly injections, and for the past fews months I've took it upon myself to space it out to 5 weeks and then the last month was 6 weeks (which I probably shouldn't have done). The last injection I had 4 days ago, and although some of my symptoms improved, my headaches and brain fog got worse. I still get little bouts of dizziness too. It also seems to have led to have affected my ear and neck, slight ear aches (not painful though), and itching deep in my right ear (can't be reached if I try dig and scratch). This is the first time I haven't had almost 100% immediate relief after the injection, so now I'm worried. Could it be that I waited to long between injections, and now my body is going in overdrive to try to restore the b12? Sometimes my anxiety has me thinking it could be something else, but it def feels like b12 issues b/c I'm also still having some of the other symptoms as well (electric shocks, spasms, etc).
I forgot to mention, the reason why I waited so long for my last injection was b/c I had my level checked right after the previous injection and it showed >6000 pg/ml, so I got scared and thought I had too much in my system. I was informed by another doc not to worry b/c I just had the shot the same day. That was the injection I had in early August. For my September injection (which I had a few days ago), I got my level checked a couple days prior, and it showed a level of 351. It's within the normal range, but still on the lower end of the spectrum. I'm afraid to ask my doctor for more frequent injections, but I'm fearful that despite my level last being showed at 351, I may have permanent damage and may require injections for then rest of my life.
Again, sorry for the long essay, but if anyone can relate, please share your thoughts. I feel so alone in this and I'm so sick and tired of not feeling normal.
