Vertiginous migraine. Husband is a gp.

It started during pregnancy 30 years ago with vomitting while driving down to my place.Thought to be pregnancy vomiting.Since then used to get headache and giddiness along with sound in the ears. Had consulted Neurologist, Cardiologist, General Physician as well as ENT surgeon.Have undergone treatment for sinusitis and migraine.For migraine have taken flunarazine for a couple of months, stemetil for some more months.Have undergone CT/MRI and other routine blood tests and all were normal. There seems to be no trigger factor or any regularity but I am sure to get it during summer and after travelling. Suffering for so long that I am wary of approaching doctors. If you can really do something different let me know as I live near Mangalore and my husband is a GP.
