I have been having sharp throbbing sensations in the back of my left lower part of my head, which actually feels 'warm' when it all the sudden comes 'on'. It lasts usually 10-15 seconds, it makes me do a double take, and then its over. I CAN feel it coming on. This last episode scared me because It almost caused me to black out for a few seconds. It is tender to the touch afterwards.
This has been happening on and off for years, but just quite recently getting stronger in intensity and havin a couple of events a month now.
Would appreciate any advice.
