About six years ago, my mother noticed a small bump in the middle of her back, an she didn't have the money to go to the doctor and it has worsened. Whatever it is, it has spread all over her back and in some parts of her chest. Could someone PLEASE tell me what its. She doesn't feel sick, but the bumps itch (not constantly though). They've turned into large lesions. If anyone knows could you please study the picture and find out, because she's had it long enough! Thanks in advance!
