I became a surgeon today, I noticed about a week ago that the tip of one of my phals turned brown-black and mushy, so I sprinkled it with cinnamon and this morning it seemed to me that the spot had grown so I took a sterilized blade and cut the affected part and sealed with cinnamon as well.
question #1 - what could've caused it?
question #2 - did I do the right thing by cutting it?
thank you guys for taking a look and as always feedback is extremely appreciated
