Does your NHS GP offer an e-consult? Where you fill out an online form with your information and details of what you want to discuss with them? Usually they take 3 days to get back to you, with either a message, telephone call, or they book you in for an appointment. When I’ve used mine they sent me a message to say the new medication prescription has been sent to the pharmacy, another time they phoned me and could fit me into see the doctor in a couple of hours. I find it quite a useful tool when I need to see a doctor but it might not be worthwhile booking an appointment.
