DS now 15, had benign tumours removed when he was a little boy from his neck and chest. He has had some more over the years but not large enough to do anything about. We found one yesterday in the centre of his chest and this is the first one we've found in a year or so. This has really upset him, he couldn't sleep last night and has needed reassurance today. With his history of lumps, we decided that we would wait until Monday to decide on whether it warranted a Doctors appointment. I was out this afternoon and he called me to say he'd had the strangest sensation and it felt like it had drained out inside him and the lump has shrunk. I checked it when I got home but it felt the same size to me. He has just had a bath and felt the same sensation. I felt the lump again and it feels tiny! Does anyone know if this is even possible or are we moving the lump and getting it at different angles? He is a bit more worried as this hasn't happened before. It is also quite painful but I imagine he's been prodding it rather a lot! I will probably call the GP tomorrow but I wondered if this sounded at all familiar to anyone?
