I was diagnosed with B12 deficiency 2 and a half years ago. I had been ill for a long time prior to diagnosis. Just before diagnosis I had tinnitus and was referred to audiology. I had an MRI but the structure of the ear was found to be ok. The tinnitus eventually went away. Unfortunately, it has returned and has been constant for over a week now. Will increasing my B12 injections be of any help?
Thanks for reading.
