Weird head symptoms for months now, Any idea what it could be?

So for months now.. I've been going to the doctor what seems like every week. I've been getting headaches almost on a daily basis. I've noticed that the headache seems to be a pain in the middle of my head, that even when I walk can trigger the pain and then a headache develops. They are usually towards the right side of my head, the middle, or behind the eyes. With the headaches, I occasionally feel as if I have an air bubble in my head and the sides right above my ears feel a little weird. I've been getting floaters for awhile now more so than usual and I've been trying to wear my contacts less because my eyes have been hurting. I've also had post nasal drip the entire time these symptoms have lasted. My ears also have been popping a lot, or when if I listen to something loud I get the feeling of when you get water in your ears but constant. It kinda feels like one of my nostrils is harder to breathe out of. I fainted back in march so there's even a chance it could be a deviated septum, but I felt as if they would've found that already since I fell directly on my nose. I've had a catscan, chest x ray, lyme disease test, EEG, EKG, bloodwork, and a heart monitor and everything has come back fine. If you have any idea as to what this could be please let me know! Thanks
