Ibuprofen isn't known as a NSAID (non-steroidal anti-inflammatory drug) for nothing. Obviously can't be used in the first couple weeks post op because of bleeding risk although I was on a steroid anti-inflammatory; probably couldn't tell the difference (since I'm at risk of bleeding).
Muscle relaxants helped me more with initial dilation discomfort than pain meds did although I combined meds for synergistic effect.
