antibiotics and water retention?

[Tough92]

Im currently 6 weeks out from my first bodybuilding comp,Things were going fine up until a few days ago,I ended up getting a knee infection the Dr gave me a shot in my quad of antibiotics and then another shot of them 2 days later,im also on oral antibiotics.Been on these for last 3 days.I ended up having a cheat meal the other day(bad choice)and i woke up 12 pounds heaver,Figure it wasn't to bad i wake up today the same weight and i look like a water Buffalo

Is this normal?How long will it last?
