My experience of podiatry services isn't very good.

In February 2014 I finally took myself off to the Emergency Care Clinic at Guy's Hospital (a £15 minicab ride, because the nearest bus stop is for me a painful half-hour walk away; but my GP surgery no longer offers appointments, so I had no choice) as I had had an unbearable pain in my foot for the past fortnight. The next thing I knew, I had been bundled into an ambulance headed for St. Thomas', to treat the huge blister on my right big toe. I was in there about a week.
Then in March 2015 I managed to drop a (full) can of aerosol cream on the same toe (only a superficial injury, but a spectacular loss of blood), and somehow got to Clapham Manor Health Centre, which to the best of my knowledge is the nearest podiatry unit to me, but again it's a ridiculously long way from the nearest bus stops.

The wound was dressed, and I was promised a follow-up appointment, and that was the last I ever heard until about a fortnight ago, when they apparently found my details while looking through their old records, and rang me to ask if I still need their services.

They are supposed to be sending out another appointment, but I'll believe it when it arrives.
