How to take care of a foot scrape?

9 days ago I slipped in the street (asphalt). I sanitized the wound, put antibiotic, went to the doctor, bandaged it for a couple of days, the whole works. Now, 9 days later, the infection went down (it really burned in the beginning) and new skin is coming. But I am not sure if I should shower or not? It is a regular scrape, nothing too deep or severe. The last doctor I saw didn't say anything about showering or not, she just said put antibiotic on it, and that's it, and she removed the bandange and asked me to air it as much as possible, and wear flip flops.

Is it ok to shower?
How will it look when it heals? Like a burn scar?
