Suggest Treatment For Slurred Speech, Memory Loss, And Dizziness For A 43-years-old.

Hi my name is Kimberly, I am 43 years old. Since November I have been really really sick. It started with slurred speech, memory loss, severe dizziness, spine burning , numbness and tingling in both arms and legs, sever bone aching, gagging while eating and a tender tongue. My primary doctor sent me to see a neurologist, she had many tests ran including ct scans, and neuropathy testing ( which hurt so bad!) the all came back normal except for my vitamin D was at a 9 and B12 deficant. Some neuropathy in hands and I believe ankles. They put me on vitamin D and 1000mcg of b12 daily and gabipentan. I started feeling better so they just chalked it up to fibromyalgia, and slight bulging disc in my neck. Now I have a two dents in the back of my head and a huge one at the base of my skull, my spine burns and my lower back deep in my pelvis just screams in pain it s hard to maneuver certain ways, along with severe headaches everyday. This does not match up with the fibromyalgia research I have done???!!! Please help I feel like I m going crazy and running up countless medical bills... Any advice on what I can do or where to get help
