Have you gotten any answers about why your mother’s pain pump stopped helping her? I’m researching/reading anything reputable I can find on pain pumps because I’m in desperate need of help with the pain I’m living with. So, yesterday I read about a person’s pump suddenly not helping anymore. The doctor did an examination of the tube that delivers the pain medication and because of a problem with the tube it needed to be replaced. It worked fine after that and has continued to do so.
