For nearly 4 months now...

it started off with feeling a little off balance and a little spaced out. Then the top of my head started to feel as if it was burning... along with dizzyness. This has made me so stressed. I have never had anxiety in my life but it's made me feel dreadful. 
 

I went to the doctors, they did nueroligical exam and prescribed me amitripline. The headaches are still here and feel of what I can describe as pressure in the sides and back of head, it's there in the morning but but no bad, but strikes at about 2/3pm Each day till I go to bed, it doesn't wake me up. Then it starts again for following day. As I said this has been going on for four months.

I've had two blood test and all ok. Is this myself making matters worse worrying or shall I Persue with doctor? 
 

it's affecting my whole life by worrying!! I find myself googling everyday.

recently been having like minor spasms in legs also? Like a muscle spasm also have a continuous buzzing feeling on front of forehead
