How is a Seroma Typically Diagnosed, New Opening with Draining? (photo)

If you see wave motion like you are carrying a water bag, then you have seroma. It's easily drained in the office. Left alone with drainage, they can slowly expand and over time a capsule will build up and make it difficult for seroma to resolve. It also can create pressure on the surgical incision and cause dehiscence and possible infection. The earlier that you have the seroma drained the better.

Based upon your written history and posted photos you have an expanding seroma that may be infected. You need drainage ASAP. 

You should be seen and reevaluated. Usually an ultrasound is a useful diagnostic tool. Most surgeons if suspicious of seroma will do a trial aspiration to make or exclude the diagnosis.  

If you haven't already seen your surgeon, call today. 

Thanks for your question, best wishes.
