Hi, Ritario. Yes, your problems sound exactly like mines, and now it becomes hard to believe that I can't normally walk just because of b12 deficiency, because I am feeling like I have ski boots on, and cant bend my ankles. That has lasted a very long time now, and I am afraid that it have an effect on other parts of my body, hips, lower back, knees.
Now I am using b12 methylcobalamin spray. I am not sure if it is more effective that just liquid, because I don't feel any other absorption apart from just swallowing it, but I must say that as soon as I have taken it, I start to feel nerve pain, so that could be sign of regeneration. The b12 patches that I used before I think was more effective, I bought them from amazon. I also used injectable b12 from Oxford Bioscience, and it felt horrible, I'm not a person, who is afraid of needles, especially if I feel so sick, but I felt as if injectable b12 didn't do nothing for me. Sublinguals I don't want to use, because they lead to teeth decay or smth.
I must tell, that the first time I went to neurologist, she prescribed me some other medicine, that was meant to heal nerves, and it was very, very effective, but I don't remember the name, smth like neurorubin or similar.
I have to say that I also don't understand why my health declined so much, given that there are vegans, vegetarians who have stayed on this diet for 14! years and still don't complain about any felt sickness.. I have been vegetarian for only 2,5 years..
And I'm very pleased, that there is a person with similar symptoms, because previously I searched for somebody that had these leg pains and difficulty to walk, and couldn't find. Because lot of people who complain about difficulty walking do so because of fatique or just heaviness in legs, but that's not it! It is more like just general discomfort while walking, though that discomfort I also feel being on my knees, because they are painful. The most fearful thing for me is that I feel as my legs become somewhat distorted.. I have fat anckles, and I know that people say that it can be caused by several things like genetics, but for me it was heavily linked with my b12 deficiency which I felt systematically, - I also have memory problems and something similar to dyslexia.. And it is very, very depressing.
So if you have good recommendations on nerve regeneration, say! I have only this, what I told - neurorubin or smth similar, I don't remember! Only know, that it isn't vitamin supplement.
And also I have only once tried nitrous oxide and it was very long time ago!
