Does this require another doctors visit?

This infection/rash thing started 3 days ago and got worse yesterday so my brother went to urgent care. They said it was cellulitis and gave him a 5 day course of ic sulfamethoxazole-tmp ds. Today it’s gotten more red and the redness has spread more. It also started to leak a little bit, nothing too crazy. It also hurts him to walk but I’m assuming that’s because it’s on the back of his knee?
Is this normal for cellulitis or should he go back to urgent care or the ER?
