I must have gone through 10+ different doctors about the same issue!! I don't have a fixed doctor but they all seem to have the same attitude towards headaches and don't take them seriously.

Unfortunately in the UK there is a process and protocol you have to get through in order to be referred to a specialist or to have medical investigations....

I'm pursuing them more now since the pain is getting worse so i really hope that will give them a push to investigate.

In the meantime my own research helps me to understand the options...
