Can feel something in my ball sack after op???

Hi guys as u know I’ve had my op to remove my nut. It’s been 10 days since the op and I’m pretty mobile now can do normal life time things. Very bored as I’m a busy person normally!! But now the Swelling ng has gone down I can feel like something still hanging in the sack. Feels like they left the tube and just cut the nut off???? I didn’t expect that I thought they took everything?? My macmillan nirse said that my histology and bloods are as good as they get but still waiting on oncologist. Anyway any advice on the tube appreciateD
