They start off raised like hives and shrink down to what they look like on my arm. They leave scars and I find it much too embarrassing to walk outside without my arms and legs covered in an Australian summer.
I saw a doctor and was given antibiotics and a steroid cream but it did nothing. Could somebody please tell me what they think these bumps are caused by? They're spreading but they don't itch.
