Jewels

So I don't know what to do..
My dog, Jewels has a weird bump on her hand I keep thinking that it might be a tic..But i never saw anything go into her paw and a tic would bubble up with blood!! I'm debating on whether or not to take her to the vet, because its freaking me out. I decided to wait a couple of days and see if it goes away, but its been about a week and it is still there!!
