hello, marley just had his MCT removed from his head, and now right underneath his scar he has a golf ball lump, it does feel fluidy or just like skin doesnt feel like anything underneath I was just wondering if after surgery this is a common thing to have a swell?

Marley could have a seroma which is a fluid-filled pocket that goes away with time. However, since he recently had surgery, it is best to have your veterinarian look at it to make sure there is no further treatment needed.

    If this is a serima they could take a few days to a couple weeks to completely go away. Sometimes a warm compress a few times a day for 3-5 days helps the fluid get resorbed faster. However if it becomes increasing in size, painful, hard, or has a discharge it could be something else and it needs to be looked at by your veterinarian.
