Hello hopefully someone can put my mind at rest,I have a lump removed in my breast and a few lymph nodes removed from my armpit.I finished chemo a year ago now.I went too see my surgeon as my armpit was hurting a bit and felt so tight,he says it was the scar tissue.A few weeks after under my arm it went very red and hot,also was swollen they said I have an infection and I'm on antibiotics now,I had to have a biopsy and they saw a mass under my arm,now I'm worried it's come back.Has anyone else experienced this.
