I had a unblical hernia when i was little (i know thats not what you mean) that took months to get better.
Had a operation last year in the same place and i was back to work in 2 weeks and out drinking the next day
Just take it easy and do as the doc says.. make sure you keep the area clean, you dont want to be rushed in hosp with suspected MRSA like me
If its not closed, just stop off at a shop on way to garage and stick it 2getha using super glue
