Thanks for the replies everyone

, I'm not worried about my feet, I just want to keep an eye on them and nip any problems in the bud, so to speak. My hubby goes on an irregular basis as he is a runner and has disgusting feet

so I'll just go with him when he goes
I have seen a podiatrist three times since I was diagnosed, almost exactly two years ago.
Firstly, because I was about to go overseas for a protracted period, I booked immediately, privately. The podiatrist I saw was very charming and thorough, and told me my feet were (are) in excellent shape and that she felt a bit uncomfortable charging me a fee, as she could offer me so little. So, she trimmed my nails, removed a tiny bit of thickened skin on one heel and moisturised my feet to within an inch of their lives.
Second time was my one and only routine diabetic podiatry appointment, where my foot status was reiterated and I was discharged, but told I could self refer if I had any issues.
And finally, some months later, was after a painful big toe that looked a bit "odd". This time I couldn't get in locally, so was sent to the nearest walk-in podiatry centre to be seen same day. The diagnosis was I had traumatised it (I can't recall that happening) and that in due course the slight bruise then present would grow up the nail and I might shed the nail. No need to return unless I had further concern. She was correct on all fronts. The odd looking patch grew up the nail, which eventually half fell off.
I keep an eye on my feet. I'm pretty flexible, so can examine and care for my own feet with ease, but I think it's important to know we can self-refer, on the grounds of our diabetes, if there is any form of "crisis" (or in my case; panic. Ahem)
