Pressure relief?

I have this pressure over the top of my head which i cant get rid off which gives a sort of tingly feeling all over and im getting a slight throbbing in the temples...its weird dont know how to explain it. The dizzy spells that i used too get on a regular basis are coming back a bit but not as frequent as before, maybe about twice a day now. I am now taking amitriptyline which has helped with my mood and has decreased the severity a bit but has not been able to get rid of the constant pressure. Is there anyone who can recommend something?
