Popping noise and sound of fluid rushing and then extreme pain and dizziness

[BubblesAndSunshine]

So a couple of years ago I was jumping rope at the gym when I heard a pop in my head and what sounded like fluid rushing. Immediately, the room light became intolerable and I became dizzy and dropped to my knees from the pain. A massive headache, emanating from the lower left base of my skull where the neck meets, continued for two weeks, and at times was the worst pain I have ever experienced. I went to the emergency room twice in those two weeks, and I was given an IV solution which temporarily relived the headache. I received CT scans, an MRI and a MRA (I believe that is what it is called). I later followed up with two different neurologists. One believed it was a migraine caused by diet, the other a migrane caused by an athletic injury. The focal point at the base of my lower skull continued to experience discomfort constantly for about a year thereafter, and migraines and vertigo would come and go. Now two years later, that area at the base of my skull (in the same exact spot) will sometimes feel inflamed or throb, and I still occasionally experience migraines or vertigo, but not to the same degree. However. since the original episode I have noticed that whenever that spot in the base of my neck aches I have difficulty focusing or thinking, and at times it feels as if my whole brain is throbbing, but not in a painful way.

As follow ups, I have continued to treat with the neurologist that believed it to be an athletic injury, and have had a follow up MRI. He did report that the follow up MRI showed some spots on my brain, but nothing that he believed to be dangerous. I am scheduled to undergo a third MRI at the end of this year. I also saw a cardiologist and had a stress test and I was told that there were no issues found and that I appeared to be in good shape heart wise. I should also note that the vertigo actually started a year before the jump rope incident, and occurred twice. Each time the room would spin constantly, and the first episode took about a week to fully subside and the second took over a week to subside. I had to remain in bed for several days at the peak of it as I could not stabilize myself to stand or walk.

Unfortunately, the doctors have not been able to provide any pinpoint diagnosis, but have ruled out tumors and what one described as "several exotic brain diseases." Basically, I am most disturbed by the lack of focus and recall I experience since this happened, or perhaps what I could just describe as not feeling quite right. I am hoping to find anyone else that experienced something similar, and find out if they were able to obtain a proper diagnosis and if they have found anything helps to treat it. In the alternative, any doctors with ideas on a test to run or something else to try would be great.

Thank you all in advance.
