Hi, so I've had this hard lump under my armpit that has come and gone for quite a few years of my life, I suppose I should have got it checked out before but never have. I don't have any lumps anywhere else but lately I've had extreme health anxiety and am becoming very worried. The lump is back now, it's very small, hard and can move around. But it seems to disappear every now and then for quite some time and then come back??? Unless I'm just not feeling it at certain times? I'd really like some help or advice if anyone has had similar experiences or is knowledgable on this topic x
