Hi, I am noticing rashes appearing on my legs over the past one week. Usually it starts with small bumps appearing in a line and then it forms a rash. It is red, swollen, painful, and itchy. I think it might be getting infected. I'm not sure what this is, my dermatologist said I am scratching myself but that is not true, i have been very careful and have small nails. Despite precautions and using T bact cream as prescribed by the doctor, the rash is spreading and getting more painful day by day. Please help me realize what this is and if I should be worried.
