Hi Zipster, yes constantly got them. They leave my skin with horrible purple marks where they have been. I have went to the GP with them once and she gave me a prescription for a special body wash but it didn't do much. I just usually smother them in Sudacrem but they are very uncomfortable. I get them 'underneath' as well which are really painful. I don't know what causes them - was tested for diabetes once because that can be a cause apparently.
