Still Draining Blood 5 Weeks After my Tummy Tuck, is This Normal?

This is likely a seroma that formed, but it may have been a hematoma that is now liquified. Sometimes the seroma can become chronic and form a lining that does require surgery to remove. I do not recommend and "sclerosing" agent for this. If it is chronic and not going away it typically needs surgery to remove. I would consult with your plastic surgeon on this. Also post operative compression garments are effective as well if you are not wearing any to help "shrink" the space any fluid may be collecting.

Thanks for your question.  It sounds like you had a hematoma (blood pocket) that it liquifing. In answer to your question honestly, this is not normal, but it does happen.  Please discuss with your surgeon his/her endpoint on trying aspiration with a needle vs placing a drain.

It sound like you likely has an accumulation of fluid/blood under the skin called a seroma. Most seromas do eventually heal and "dry up" with serial aspirations (removal of fluid with a syringe and needle). However, if a seroma persists then sometimes it is best to go back to surgery and remove the seroma cavity lining and replace a drain.  Discuss your concerns with your PS.
