I am a 36 year old male, with a small (size of a pen tip) ulcer type wound on my left ear helical rim. It has gone on for 3-4 months, painful to touch, non bleeding , but if I squeeze it, clear fluid comes out. I sleep on that side. It hurts, but not too much, say 0/10 normally, but with squeezing, about a 1-2/10. It has not increased in size, and has a surrounding bump that would be 1/4 size of a pea, and has been this way since I found it. Any ideas?
