Hi- In The Last Few Months I Have Notice A

Hi- In the last few months I have notice a splattering (for lack of a better word) of freckles on my ankles (top and sides of ankles). They are not raised and do not bother me in anyway, just odd that they appeared. I am 39, so thinking its sun damage but wanted to check. I am currently taking Vibryd and Lamictal for Anxiety and Mood. Thoughts?
