Head tightness

Hi I’m m20 and have dealed with anxiety for a few years but just recently it has started to become extremely bad. Just recently I’ve been feeling a tightness in my head and slight headaches. Obviously my anxiety tells me it’s a brain tumor or something worse than it probably is but I can’t stop these thoughts occurring. I was just wondering if anyone else with anxiety suffers with a kind of head tightness as well (the feeling of it not an awful pressure but a pressure nonetheless on your head) and was just wondering if these are normal anxiety side effects or if I should actually go see a doctor about it.
