I experienced similar symptoms for several months and went to see a doctor about it, they couldn't put a finger on it so they just called it a headache. For me I found out it was due to chronic stress worrying about the tension which caused the tension to exist further and it created a very destructive cycle. If you're worrying about anything, it can be the cause of the pressure/tingling. Stress and anxiety have extremely powerful sensations associated with them. If you're in the same boat as I was you need to let go and accept whatever is going on in your life or whatever you're stressing about. It took me 7 months but my symptoms went away, meditation really helped. Good luck man
