I am unsure of the indentation on your forehead, it seems to be of recent origin and needs more evaluation. I am sure you must have had the idea of having imaging done to know what the indentation is about. In any ways, the whooshing sounds in ears and dizziness
are classical symptoms of vertigo
. You need to see an otorhinolaryngologist (ENT doctor) to make sure you do not have any serious condition and to have yourself treated.
I hope this helps. Take care.
