Can I Drain a Seroma Myself?

There are several good reasons you should not drain the seroma yourself. As physicians, it is generally advised that we don't treat ourselves and family. Or as the saying goes: A doctor who treats him/herself has a fool for a patient.
Most importantly, it may not be a seroma and this could result in other unforeseen complications which you are not prepared to manage. Seek you doctor's advice. If it requires drainage, they are best equipped to perform it and confirm the diagnosis. If perhaps after multiple sessions, this is established and requires ongoing drainage, you can bring this up with your treating physician. Hopefully, you will never get to that point.

You should see your surgeon not only to have the seroma drained, but to also assess your condition to find out why you've developed a seroma and to make sure you're okay.

Although drainage of a seroma in the hands of an experienced plastic surgeon is a relatively simple procedure, it could be very dangerous in the hands of someone who doesn’t know what he’s doing.  The potential for injury to deeper anatomic structures is real and could potentially be life threatening.  It could also result in the development of severe infections if sterile technique is not followed.
For all these reasons, if your experiencing this type of problems it’s critical that you consult with your plastic surgeon.  This will ensure that the correct diagnosis is made and the proper treatment given.  This will ultimately result in the best possible treatment for this condition.
