Sorry but as you're already seeing a doctor about that it is against the
rules of the forum for us to answer it. Due to this I'm now going to close this thread.
What I do suggest is you go back to your doctor or possibly see another one in the surgery and discuss it with them again and tell them how much it is really affecting you and then hopefully they will be able to do something to help.
If you want to discuss this then feel free to PM me.
