Hi thanks for your comment. I just keep worrying about a reoccurance. I did start playing tennis recently. I do still have a seroma still and have a golf ball sized hardened tissue of some sort inside of it. But this crunchy/popping feeling is on my left side (seroma and repaired hernia on right side of midline abdomen) I push on the area that’s popping but the swelling doesn’t reduce. I live in Okinawa Japan so I’ll have to wait till august to see the surgeon at dr goodyears office
