If you’re non weight bearing for a few days then I’d make an appointment. Sometimes it is easier to deal with these sorts of injuries earlier to prevent the need for physio later.

I know how you feel, I slipped in the shower in a hotel and landed with my shin on a metal shower screen rail. It wasn’t painful to walk on but the bruising was terrible and it was so painful to touch. I didn’t want to waste anyone’s time. I’m glad I went to the walk in clinic because it put my mind at rest, I had damaged the surface of the bone, nothing too serious but I needed some physio and massage to get it looking normal again.
