I've been feeling dizzy and light headed for over a year.  Symptoms keep changing. I periodically get fullness in my ears follows by positional vertigo.  Attack lasts for a couple hours.  I also have sporadic tinnitus.  On another note, I always have been sensitive to plane take offs and sudden movements during the flight with no lasting issues, but most recently about an hour after the flight a fullness/ pressure feeling in my ears followed by a vertigo happened.  On the return no vertigo but a headache for 2 days.  I'm unable to have sudden turns too fast, jumping without lasting sensitivity.  During bad light headed spells I'm unable to bear down without everything moving.  I have had multiple MRI tests, balance, special cat scans to hear all normal.  In recently started cervical therapy.  

Has anyone had these symptoms and found a solution?  I have another flight planned with a cruise and am extremely concerned about how my head/ears will be.  

Can Anyone help me?
