[|Human|] My husband had a small knot on his back a couple nights ago. I rubbed it out but it seems to have rotated to his side where his ribcage is and is now swelled up to under his arm pit. Everything I keep researching is saying pleurisy but it seems like a fluid pocket that you can physically feel on the outside not inside of the ribcage. What is this and does it require medical attention? If not then what should we do to make it go away? He s in constant pain
[|AI|]  Hi. Thanks for your query. Noted the history about your husband having small knot as you have explained. Such a knot could have been an infected sebaceous cyst that also causes the lymph nodes to swell. I would advise him the following:Consult a General Surgeon for clinical evaluation, examination, confirmation by Ultrasound and to get this and the lymph nodes treated medically to start with to control infection so that the knot can be removed later. Once removed this can be sent for histopathology to confirm what it is.
