I have had a severe headache for the past 12 hours that feels like a vise grip over my scalp. I have taken 12 Tylenol over the past 12 hours and it has barely reduced the pain. The headache is all over my head, and I have a history of high blood pressure but no vomiting, fever, or dizziness. I have had similar headaches before over the past 6-7 months, but this one is the worst. What could be causing this headache and what should I do?

Can peripheral neuropathy stop you from walking?

I am an 84-year-old woman under stress with a son living back at home. Today, especially, my pulse is all over the place and I keep feeling as if I am about to faint. (I have never fainted in my life) Is there cause for concern? I don't want to call the EMTs and have ambulances and fire engines come.

I have a high white blood cell count, ESR, NEU, LYM, and C Reactive Protein, and low vitamin D. I experience dizziness, nausea, headaches, numbness with pins and needles in my fingers, hands, feet, and lips, and I'm exhausted. I've had a negative temporal artery biopsy, seen specialists who ruled out thyroid, blood, ear issues, and neurologists who thought it was ear-related. An MRI showed white matter, and I have migraines. I'm positive for MTHFR but don't have a clotting disorder. I'm 45 years old and use a cane, and my mental sharpness has declined. I'm being treated at the National Naval Hospital in Bethesda, Maryland, but no one has been able to diagnose me. Any suggestions?
