Head Burning and Aching Constantly.

Hello Doctor, I would like you to help with my condition which I'm about to explain; it's been more than 5 months that my head is burning and aching constantly, the burning isn't on the skin and applying anything on skin doesn't make it any better. Therefore, my mood changes rapidly and most of the times I find myself irritated; I cannot sleep well, I wake up 4-5 times during my sleeping. I am not hungry at any time I can easily go without eating. I'm having certain hallucinations, also I don't feel anything at some point when I find myself staring at any object or thin air. I did went for MRI scanning and the report said that it was normal. I took B12 supplements namely neurotrack, neurokind, Bcomplex, etc. but my condition hasn't improved but gotten worse by now. I do get used to this burning and aching head in 2 days, but it just amplifies within 4-5 which becomes unbearable for a certain period of time. Also, when I wake up and at any time of the day, it amplifies out of nowhere.
