Good news!
Just got a call from the GP I saw this morning who said she called the Royal Free and spoke to the consultant's secretary who in turn spoke to one of the Registrars on the team and they have arranged an appointment for me 25 March.
Considering they only got my referral through 5 Feb and I was hoping to be seen within 3 months I am pretty impressed with both my GP and the hospital for getting me seen so quickly. The NHS can come up trumps sometimes!
Feeling hopeful for the first time in ages
