possible increased intracranial pressure?

I have had many strange syptoms (symptoms) over the past 3 years. The most bothersom is a non-spinning vertigo (like being on a boat) cognitive problems. I also have anisocoria (with assymetric pupil) headache, empty sella causing a mild pituitary insuffienciency, stiff neck, daily headache, eye convergence problem, visual wavy lines (when i close my eyes) and tinnitus. I also have a past history of Lyme disease with a positive IGG test. My question is..doesn't this all sound like I might have increased pressure in my head? no doctor had every mentioned this as a possiblity. The best thing anyone has come up with is migraine. I have taken several migraine preventatives and no change in symptoms..Any advice on how to proceed?  I am a 42 year old male in good physical shape other than a mild hypothyroid problem and the mentioned pituitary insuffiency.
