Pressure behind left eye that shifts to right eye from day to day with a headace

I have been to a bunch of doctors in the last month . I saw a eye doctor and had a CT scan but nothing has been found. still in pain and have the pressure behind eye. Its been like 3 months. I have a MRI coming in 2 long months. The eye doctor sayed theres nothing wrong with my eyes. He ran all the test but nothing. I have know idea whats going on.

Mine started like that about 5 years ago. Now I have stabbing pains too and the intensity is much worse. 2-3 days on left side, 2-3 days right. I have always suspected parasites and have done a lot of zapping in the past with little success but after passing some ascaris in urine and bm am pretty sure I need to do something. I just started zapping and taking Black Walnut and Cloves, will also periodically do a homeopathic treatment and see if that combo helps. Won't know until my next cycle since mine are usually post-menses. My last ones were so bad I'd have gone to the ER if I wasn't in so much pain.

Well i had an MRI and the test showed that i have abnormal blood vessels in my brain.
