I have these bumps raising out of my skin on my upper back, shoulders, and some smaller ones on my chest. A doctor online once suggested that it might be keloids, but after searching online and seeing examples of other peoples keloids, i don't think it is. They are in many different sizes, the largest being the size of a pea grain. they look soft, but it is really hard under the skin. they are darker than my skin color, especially the edges of them. I'm light brown in skin color so the edges area dark brown. Sometimes they itch, like when u touch it. But Sometimes i dont feel it at all....can you help me determine what this skin defect is? Is it dangerous? Is it treatable?
