Suggest Treatment For Persistent Vertigo

I suffer with vertigo from time to time. I took a family trip from Tx to Calif and back going to many high elevations. A week later i had a bad attack where i had sat down in my recliner and i had to hold on and began to panic. I had sensation the floor opened up and i was plunging at speed of light. This was worse and different. Today i experienced when staring at a door, it all became wavy and dancing. Sometimes the top of my head feels weird. Is this all part of inner ear or brain malfunction? What specialty Dr should i see? I am 62 and female, dont take any prescriptions and BP usually normal.
