[|Human|] A slight lump in the front part of my armpit after having a pacemaker placed 3 weeks ago. It makes my arm and shoulder ache when I palate it. Is this from the surgery and normal? It was not there prior to surgery and is fairly close to the surgical incision.
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query. No, this is not a cause for concerns since this is an expected part of tissue healing, and it represents subcutaneous fibrous or collagen tissue accumulation. This is not serious issue and should not be treated. Only if there are skin changes such as redness, pus discharge or pain and fever then you should see medical attention, otherwise, you can wait and see if such symptoms will occur.  I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
