[|Human|] I have a moveable lump in my armpit, this has been there for over a year now.  I have seen three different doctors, none of whom could feel the lump, I was however referred for an ultrasound (last year), this did not show any lumps at all.  However I still get some pain in the armpit and it looks fatter than my left armpit
[|AI|]  Welcome to Chat Doctor .1. As you said three doctors has examined and declared there are no lumps, and an ultrasound did the same.2. In this case I would recommend an MRI (which gives better anatomical differentiation of the body, and it will 99+% rule out presence and absence of the lump. 3.after that needful action can be taken.4. Furuncle/carbuncles/abscess could be seen in that region, but as you have not said evidence of any pus discharge and redness/tenderness it can be ruled out. Anything to ask ? Do not hesitate. Thank you.
