Days after Perianal abscess drain! Help...

So I recently had a Perianal abscess drained. After excruciating pain and an ER visit the doctors finally got it right. It was huge infected abscess.  It got drained Wednesday afternoon.

Thursday I felt ok just a little discomfort but no more pain.

Then Friday I was in a lot of discomfort.  I was had FOUR bowel movements on Friday and it was so frustrating because I had to change the gauze and clean the area every time. 

Friday the wound started to sting. 

Now Saturday I woke up and the wound was hurting a little so I got in the shower after yet another bowel movement. It stung while in the shower. 

Is it normal ? 

Will this go away soon?
