Aww, the worst bit was them putting in the needle with the anaesthetic to numb the toe, after that it's all numb.
That said, I'm not that squeamish but was in two minds whether or not to watch. Didn't help I was a bit delicate after a rare few drinks on my birthday the day before.
Careful choice of footwear is a good idea, open toes sandals are good. I had mine done in the winter but my furry boots gave me plenty of room and protection so nothing was pressing on my toes. I remember being terrified on the bus that someone was going to tread on them after!
Mine needed dressings on for quite a well after, changed daily (they change it for you initially, did me anyway), it was a good few months or so and I had to buy my own dressings in the main, to do myself. My GP did prescribe me one box full (Boots had to order it in) and I got another box on Amazon, these ones in case she needs to get any at any point:

I was dressing two toes at least once a day though and had a minor infection but I'm really prone to infections anyway. They can look a bit yukky while healing but they were fine, a good idea to know what to look out for, especially in a diabetic, as I was worried mine were yukky at one point and infected but they weren't :)
Always best to be on the safe side though, I had issues with a bit of burning from the chemical which stops your nail growing back but it all cleared up fine.
Podiatry were great with me and saw me more often as it's difficult for me to get to my feet.
