This has happened occasionally before. I know what to do: put ear drops in for a few days then go to the nurse and get it syringed.
Being a new patient to the practice (I sent the small rainforest of forms in last Friday) I know I need a 'new patient medical' so I ring the surgery for an appointment, thinking I can kill two birds with one stone.
"I'm a new patient in the practice. Can I arrange an appointment with the nurse for an initial medical?"
"I can fit you in next Wednesday."
Over a week away!
"I'm sorry, but I can't wait that long to have my ear syringed: I can't hear anything on one side." There is a hint of restrained anger. Only a hint, mind.
"I'm afraid you have to make an appointment with a nurse to see if it needs syringing first."
And thus I go quietly mad. Or rather, echoey, head-hurtingly mad. I must now wait for an appointment with someone who will tell me what I already know, and then have to wait for an appointment with her (presumably a further week later) to resolve the problem. Meanwhile I can't hear much except my own ringing ear.
When the NHS works it is brilliant; when it doesn't it is the most frustrating thing in the world.
