I have had this before so its not new. I have severe neck problems that cause pain in head and down arm and I am guessing it could be related as neck is bad at moment but whenever i go from sitting to standing I am getting sharp pains in top of head in time to my heartbeat for a few seconds. It usually lasts for a few days then goes away.
My bp is fine I have been taking it 3 times a day recently.
Just wondered if anyone else ever gets this. I have had mri brain scans in the past ( last one 4 years ago) with no issues.
