Thanks for writing your query.
From the symptoms you have described, it indicates that you are having motion sickness
or travel sickness.
While travelling you should try looking outside of the window in the direction of the travel. If possible close your eyes and take a nap.
There are medicines which are helpful in motion sickness like dimenhydrinate, cinnarizine
, etc. But you should take medicines only under medical supervision.
Also get yourself examined by a Neurophysician and an ENT specialist
I hope this is useful to you.
