Headache every day

Yall I have a freakin headache every day it's it's just not going away I got diagnosed with iih like November 2023 but my last neurologist apt he said that they didn't find anymore fluid all they seen were that the veins in the back were tight so idk if that's why??? Like if I laugh too hard my head starts pounding like somebody hit me with something across my head or if I sit down it hurts and when I lay down i feel soooo much pressure it's make me so scared now I just been having dizzy spells and headache everyday , ears ring like heck but I do have high blood pressure as well smh it's so depressing I'm just 23.. anybody else have these problems ???? Let me know.
