snapping

For 10 years, I have been dealing with something in my brain. I sometimes feel swelling, tingling, and sometimes snapping in my brain. I have been asking if I could get a brain scan to see what's going on in my brain, but to no avail. I don't want to sound like a hypochondriac, but something...

Please pray for my health, my eyes hurt are very dry at times, I can't seem to find a good eye doctor, I'm dizzy, have a snapping in my head it sounds like, tired a lot, doctors haven't been very helpful so I'm leaning solely on God and Jesus Christ.
