Much like a hematoma, a lump can be felt under the skin, usually associated with discomfort, warmth, and high blood sugars. No warning except highs and site discomfort!


Can occur to anyone. More likely in anyone who has ever had a skin infection (infected cut or scrape) in the past.

Usually starts when the site preparation is poor, sterile technique is not used, or the infusion set is not changed as recommended.


Remove the infusion set. Pinch the lump under the skin to remove as much of the fluid as possible. Check for color, pus, or smell in any fluid that comes out. Apply a warm compress and call your doctor immediately if you even suspect an infection.
