Thank you doctor,
My vitamin B12 level was 154. The other blood tests are normal. Before the diagnosis, I was feeling a suction on the left side of my chest. But now, after the treatment, it is normal. And when I tried to sleep on the left side, it was quite uncomfortable. This problem got cured after the treatment as well but, not completely. I want to know if all these symptoms are related to vitamin B12 deficiency or another problem.
