My DD had her appendix out 12days ago. She got sicker & was eventually diagnosed with abcesses. She was taken back to Theatre & had her wound reopened & gas a drain attached-it's draining 15ml + foul pus daily. There's also an internal abcess behind her bladder which seems to cause the most pain (peeing is painful). Anyone experience this before? I'm just wondering how long it might all take to resolve...
