healing process of foot tattoo

I just got my first tattoo on my foot about 4 days ago. Can anyone give me advice on what to expect for healing? It doesn't look scabby or itch at all, but my foot is still a bit swollen and I have a little pain around my foot and ankle (probably because I have been walking weird to make sure nothing rubs it). I just want a run down of what to expect and if I am concerned over nothing, after all, getting a foot tattoo for my first tattoo was an interesting choice. I just want to make sure everything goes smoothly!
