I am thrilled to hear I'm not crazy! I've had itchy ankles a few times a year for years now. I am healthy and don't have anything mentioned below. I also don't get red bumps. I just itch my ankles until they are raw. I did do something crazy that seems to help. I saw the healing powers of urine, yes, I mean pee. I saw a story on TV that it helps take the sting away from jelly fish and bee stings, so I figured I'd try it...and it works! I poured my urine all over the area and it took the itch away. Problem is, the next day after I wash, I have to do it all over again. I let it dry on my skin with a towel under my foot and it doesn't smell, but who's going to be at my feet. LOL
If anyone knows what causes this I would love to know and maybe I can take a pill instead.
