Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for difficulty breathing, chest pain, coughing up blood, fainting, severe confusion, or bleeding that does not stop with the measures your team provided.
Contact your surgical team promptly if you have worsening redness, warmth, swelling, pain, pus, an opening incision, or a fever that meets the threshold in your discharge instructions.
Also call if a drain stops working, falls out, develops foul-smelling fluid, or suddenly produces much more blood.
Seek urgent assessment for new pain or swelling in one leg, especially in the calf.
Mention them at follow-up, or call sooner if they are increasing rather than improving.
Mild swelling, bruising, tightness, numbness, and small amounts of drain fluid are often part of routine recovery.
Every sign above is quoted from the sofidex article on Panniculectomy. If you are not sure, err upward — it is always reasonable to be checked.
