In addition, when you suffer from anxiety, it’s not uncommon for your head pressure to get worse the more you worry about it. I’ve been thinking i too have a brain tumor or something weird. I just want to let you know it is the anxiety that you are having. I have had the problem for 50 years. You may want to look into parasites. I suffered what was called a catastrophic brain aneurism, and should have died on the spot. Vertigo can also be triggered by problems in the inner ear.
I am 45yrs old and a smoker of less than a pack a day. Primary brain tumors are often benign but can cause seizures, ongoing headaches, or loss of coordination. If you have a good thermostat best like the new ones.
