Found a Lipoma After Tumescent Lipo. Did This Cause It or Uncover It?

Removing fat does not cause more fat to appear.  The lipo likely exposed your lipoma.  It is easy to remove.  The massaging machine will likely change it very little. Thank you for your question and good luck with everything.

It is possible that a lipoma can hurt, these are often angolipomas, and benign. It is possible that lipomas can be unmasked by the surgery reducing the mass around the lipoma.  Tender lumps under the skin after liposuction could be localized inflamed residual nodules of fat as opposed to an actual lipoma, but both might be treated similarly by a secondary focal liposuction technique.  The differential diagnosis also includes a small hematoma which may resolve or may need to be drained and sometimes treated with antibiotics, as a possible diagnosis is an abscess. Your surgeon knows more about your condition  by examining you and is better suited to diagnose and recommend treatment than  any physician who is answering your questions without seeing you, so make sure you followup with your surgeon. Certainly you could consider having a second opinion if the symptoms don't improve soon, and more urgently if the symptoms increase.

Liposuction will not cause a lipoma to form, and though it is possible that the lipoma was unnoticed until after your liposuction, it is important to determine if the tender lump is a fluid collection, bleeding or hematoma, or scar formed in the area treated. Massage will have little effect and if painful you may wish to stop. See your surgeon to have the lump checked out fully.
Best of luck,
