Its not much of a problem as it is a curiosity. I've had only a few recurrences in the past 8 years or so. They're the size of a pea and not from friction. They occur under toughed skin of big toe tips only. They don't hurt, barely feel them after I lance them. When I do lance them, clear to yellowish liquid drains. The area hardens as it heals and takes a couple weeks to do so if they don't refill which sometimes happens.
I looked over several possible diagnoses but none seem to fit lupus (I'm male), herpes (been screened), chicken pox (never had it/not exposed to it recently), and aside from fish oil and some Alleve, I take no meds.
Anyone have an idea?
