I am 30 yrs old and for the past 3 weeks my blood pressure has been 90/60, 89/58, 106/70 or 96/58

I had vertigo prior to my blood pressure drop and I also have degeneration in my cervical spine.  I wanted to know if all this can affect my blood pressure.  I was also slightly anemic. My blood level is 11.3 from my last checkup. I can tell when my blood pressure drops. I feel light headed and get a sinking feeling.  I have been comlaining of this sinking feeling since 2 months now. My doctor did ekg, sent me for mri of the brain, ct scan of the cervical spine, uterus scan.  I have no fibrods, my brain scan was normal. ct scan had mucus thickening.  I really don't know where to go now.  I am tired of all the visits I've had since february.  Please help.
