Chemical: They probably used either phenol or sodium hydroxide to kill the matrix (nail root) in the corner, preventing another ingrown toenail in the future. It is usually applied with a cotton-tipped applicator (q-tip). It actually delivers a chemical burn, and some of it may have gotten on the border of the healthy nail--it should be fine, and it will probably fade away over time...

Chemical burn...: or dried blood from the procedure is the most likely culprit
