line of 4 to 5 small, looks like a bruise, on upper thigh. occasionally stings. no itch, no change or color, no raised or rough patch. ranging in size from a dime to a quarter, all in a row, mid thigh to knee. have had for few months and no idea where i got them. they haven t really changed in all this time either. at first thought it was a bruise or hit my leg on something but now a bit more concerned
