I had one a long time ago, luckily I was in the RN at the time and had it cut out within a few days of going to see the doc.
Mine was towards the centre of my upper eyelid - so they kind of peel back the eyelid towards your forehead and then cut it out, I'd had a local anaesthetic so didn't feel a thing, it wasn't even all that uncomfortable. Happy to report that I've never had a recurrence of it either
The worst thing about the whole procedure was having to go across to Haslar on the ferry in uniform, so on the way back I was in uniform with a bloody great bandage across one eye - cue lots of "bloody hell it's Admiral Nelson" from the ferry crew
