Hello, Littles! I was born with part of my left arm skin "glued" to the arm bone. I always had this "fold". And I always was ashamed of the aspect of that. I tried exercises, diets, but even with 130 lb it was still there. My arm looks the same. I live in Brazil, where the sun is so hot all the year, and I never had the courage to use a shirt that shows my arms. But now I'm tired of hidding myself. i was born this way, my skin and my bone are glued at that point, and that's the way I am. Sorry for eventual wrong spelling of the words in english. Thanks you brothers and sis for letting me open my heart. Paws Up!!!
