Headaches, numbess, memory loss.

I was a very healthy 39 yr old when my family moved to a new area in the same state 3 years ago. I suddenly came down with severe headaches, the worst you could imagine! For the next 4 months I went to several doctors, all of which tried several ways to treat me for migranes. Finally, after an mri, I was diagnosed with hydrocephalus.
The diagnosing dr. recomedended a shunt. So,within a week I found myself having brain surgery. I was told that it would relieve the pressure and solve the headaches.
That was 3 years ago, since then I have had no relief, I have changed doctors, they are at a loss with me. I am suffering with severe memory loss, and have constant ringing in my ears. My brain feels like it is on fire most days. My fingers and toes constantly go numb and yet my doctors can't explain why.
I am beginning to think it is enviormental. But maybe that is my pesimistic nature. I have a very supportive family, because with the pain, most days I am not very functional. People, I was a vibrant, healthy, active, mother 3 years ago. If you look into hydrocephalus, you don't just "get" it. I have had no brain trauma on my life.
I don' t really know why I am reaching out here, some of you seem like decent people, just venting I suppose.
