Had this the other night. Went to bed with slight headache. Woke 2am with severe pain in back of head. Painkillers didn't touch it. Could not get comfortable, though slightly better standing.
I've had this type of head pain before but it normally responds to painkillers and, this time, I suddenly went unbearably hot and was drenched in sweat. I panicked and started hyperventilating and my hands and feet went numb Eventually, I was very sick then cooled down immediately though head pain remained but subsided enough to sleep.
Have had dull pain on and off ever since. I have a history of cervical disc problems which has recently flared up. I also have hearing loss currently under investigation and I have a scan coming up.
Any ideas? I really thought I was dying
