Over the weekend , with a combination of a lot of walking and a different pair of shoes, I developed the occasional sharp pain in my right foot. By the time I came home, it was bothering me and I looked to see there was a blister on the sole of my foot. No change the next day and I was wondering how I would fare walking to and from the the station, or whether I should go in at all, but I found that the 3 year out of date blister plasters I still had did an excellent job of cushioning. While I was aware of an uncomfortable pressure, especially when I stepped on the dimpled areas to alert the visually impaired of a road crossing point, I was relieved that there was no longer a sharp pain, and also that, being sighted, I could side step all the ridges and dimples with ease. I was also grateful that I was sighted and not in nearly as much pain as my brother-in-law has been for months awaiting his hip replacement. If he can get home from hospital the same day, then I could surely put up with a blister.
