What to do if I got an infection from a nail salon?

I got a pedicure 1 week ago, in which the nail tech (owner) hurt my big toe during the pedicure, the following day my nail became red and inflamed. I contacted the owner as she is the one who did my nails, she stated I go back in to the salon for her to review. She tried to treat the issue herself as she placed my foot in a warm salt bath and poured over hydrogen peroxide, she said it should be better by the end of the weekend. As the days went on the toe got progressively worse, it became purple to the point I had to go to the Urgent Care and get the toe drained and am now on antibiotics, I had to pay for these expenses myself. What can I do in this case am I able to demand the medical expenses be paid by her?
