Can anyone tell me what kind of bite this is? I work at a indoor restaurant in Georgia and came home with this series of what looks like bites above and below the back of my knee. It s causing a quite deal of pain/ irritation and some burning. Benadryl Cream doesn t seem to help any. The spot on the back of the knee looks like mosquito Bites condensed together and a rash surrounding them. The spot on the back of my upper leg is larger and looks like it raises off my skin more. At a glance the bites look smaller than average mosquito bites with a surrounding rash but when I press down on the area it feels like one hard lump under my skin. All of This was not on my legs before I went into work. Anyone have ideas?
