This made me feel nostalgic I burnt my foot too a few years back, got a massive blister and took loads of gory pics to keep as a memory. I made a post too I think, but here's my fav pic!
Looks like you grew a potato on your foot. Isn't that like a second degree burn though? I would imagine it should have been debrided, it would have healed better.
Got to see an inmate get "melted" (he later died) with a pot of boiled potatoes. The starch in them was rendered out and made it stick like napalm. Good pics op.
