1992.
I saw a doctor in the Midlands when I caught chickenpox when I was 8 years old, in 1964.
I've been to the local surgery 3 times since I moved to Hebden Bridge in 1986. The first time was in in 1989 when I got back into cycling and got a bad dose of sunburn when I stupidly did a 5 hour mid-summer ride without any protection. That time I was seen by a nurse who put cream and dressings on the nasty oozing blisters that resulted.
In 1992, I got a bad case of 'strep throat' which I ignored for a few days until it felt like I was gargling with barbed wired and I could no longer swallow. I saw the doc and he put me on antibiotics.
While I was there, the doctor took the opportunity to update my medical records since the NHS didn't have a clue what I'd been up since my previous doctor's appointment in 1964! I told him that my hearing wasn't great so he sent me for a test and I went back a 3rd time to get the results which told me what I already knew which was that my hearing was impaired, but was functional!
And, that was that!
