I was treated for cellulitis (Staph) on my arm two weeks ago with antibiotics via IV as an inpatient for four days, then 10 days of oral antibiotics.  The swelling has gone down but now I have a painful, hard bump on my elbow.  Is it possibly a pus pocket?
Hi, If the area of the bump is warm, tender to touch, red and has a fluid consistency then it could be a pus pocket the medical term for which is an abscess. It would require Chat Doctor. Thank you for your query.
