Hi

I noticed this brown patch on the side of my finger, I think I've had it for ages, but for some reason I noticed it yesterday and began panicking, deffo doesn't look like a mold just a smallish-medium small patch of very light brown skin.

Worried about what it is. As I say think it's been there for ages as I remember worrying about something like this before but can't remember if that was something different. Could be a sunspot but I'm only 23 and have never used a sunbed. Have got sunburn in the last before
