You're a tough cookie!
A brain injuries are so hard. First the symptoms are terrible, but since they're largely invisible a lot of ignorant clods will treat you like a lazy, whimp.
I really admire your fighting spirit and I hope that you can turn some of that toward getting yourself some care. Most family doctors know squat about TBI. It's not something that you just "get over."
As you've been searching the fourm, you've probably seen that there are a lot of treatments and medications from speech therapy to B12 to QEEG that might ease your symptoms and maximize your recovery. I can't remember, have you even seen a neurologist?
Given that you fell, has anyone considered that the tingling might be neurolgical injury from whiplash?
I now it's difficult to meet family and financial responsibilities and still get the rest that is so crucial in the aftermath of a concussion. Sleep whenever you can and get medical help - you're worth it!
Cheers
