This is likely a tooth root abscess. This is why it got bigger and smaller and bigger again. It will fill with pus, then drain (get smaller) and then fill up again. Unfortunately such infections are seriously painful, and bacteria can get into the blood stream and cause sepsis which can be fatal. The tooth that is affected will need to be pulled as fast as possible so that she will not get a general infection and also will get relieved of pain.
