I have it too...same side as you...from the pinky finger to the wrist on both hands. No endo has ever been able to explain it to me, and believe me, I've asked! LOL It came with the Graves but has never gone away.

My daughter has palmar erythema. She's almost 2 but there has been no explanation as to why she has it. I noticed it when she was 6 months old but thought it was due to crawling on the floor. Nope, she still has it.
She is also failure to thrive, has "asthma" (not sure how I feel about this diagnosis), chronic diarrhea and some abnormal labs. The pediatrician is currently reviewing her lab work and symptoms and will be getting back with me (he doesn't seem too concerned; feels the asthma is causing her poor growth).
I asked him about her "red hands" and he said he has no idea why they're like that. Since they go purple sometimes he mentioned raynaud's.
I have red palms when I flare up (I get the darker dots too) and my finger tips get red circular patches on them (with normal colored centers).
I have low thyroid function though so I don't know why my hands do this.
I get something like this, but only on the soles of my feet. It's like a red swelling, with heat. Somewhat uncomfortable, but not that painful. Does anyone know anything about this on your foot? I am hypo. by the way.
