I have been stupid. I spotted a squished hard old blister on my little toe, noticed the top was entirely hard skin, and decided it was a good idea to cut it off. It was not. I now have this little triangle of subdermis (or something - IDK) peeking at me. I panicked and trapped it in a plaster and toe socks all night, then had to walk to work this morning in surprisingly tight shoes. The toe has hurt more and more over the day and is now quite unhappy. What do I do with it? All options (inc amputation) will be considered.
