a red dot appaired in my palm. I wonder if it means anything?

A few weeks ago, I noticed a red dot had appared exctly where my fate-line and head-line meets.
I do have a little bit of rash betweeh my fingers and sometimes small blemishes, but this was not a blemish, and it is not in the same area as where my skin is affected.
The position is very odd and I can't help noticing it.
Anyone who knows if it has any meaning or is just pure coincidence? It is in my left hand and I'm left handed.
