Over the years it’s happened countless times, the skin on my arms and legs become mottled. I’m not wanting to self diagnose, but I am curious to what could potentially cause this.
In general, multiple things, from vitiligo to fungal infections. Since it solves by itself it’s not vitiligo. This page has a very long lists of possible causes. You may want to see a dermatologist.
My girl friend tells me that past use of birth control pills can cause this with exposure to sunlight. She hasn’t taken the pill for over 20 years but still gets the mottling on her arms. I really don’t know ust what she tells me on this.
Ah wow, I don’t think I have the patience to go through it all. A trip to the doctors shouldn’t hurt I guess.
Is this happening after exposure to the sun? I knew a guy who had uniform skin until he got a little to much sun. Some of his skin would tan a little while other spots would turn reddish like a burn. Afterwards his skin would seem mottled for quite a while until he got paler all over.
