Yeanh we seem to have a lot of the same symptoms. The neck and face burning, pulse at night. Oh yeah.
If you are feeling your pulse at night (as I was lately), don't worry it's anxiety and please do not google this at all. You might also hear your heart beating in the back of your neck or head. Again dont google this. It's caused by anxiety.
You can have blood pressure which is induced by anxiety, or, you can have standard health problems that cause higher blood pressure. If you do have anxiety induced high blood pressure, it's 'safe' because it's temporary and only based off anxiety so your palpitions are harmless.
Does your heart speed up after eating or walking up the stairs? I bet it does. The 'anxiety heart rate' seems to be very 'responsive' to eating, moving around, etc. Your always on edge for it to beat faster.
Eventually, you'll get back down to a low pulse and wont hear or feel your heart beating.
