Hi doctor,I have developed some brown patches and freckle like spots on my left hand overnight. I went to bed last night with a new light brown freckle on the palm of my hand and woke up this morning to it being darker and there being more freckles and patches. There are a couple of patches on my ring finger and it looks like a stain. The brown spots seem to have become darker over the day and a couple more have appeared. What do you think this could be? As far as I am aware, I have not been exposed to anything. Thank you.
