On Saturday I slipped on some steps and the top of my foot was rammed against the edge of a hard surface. It swelled up and was painful, but once I'd recovered from the shock I was able to cycle home ok. The swelling eventually went down and yesterday I was able to drive. Today it's still looking a bit swollen and bruised (see photo) and there's a small painful lump.
Tomorrow I need to go to work which involves a fair amount of walking to get there and back. Should I just carry on as normal, and expect it to heal itself, or go and get it examined by a doctor to see if it needs an x-ray? I don't think any bones can be broken, but don't know whether the lump is an issue I need to worry about.
