Had A Pedicure Two Days Ago. Only On One Foot

Had a pedicure two days ago. Only on one foot toes are reddened to the base of each toe and reddened areas of blistering are forming at the base of my toenails. I was given shellac pedicure and they used a light between coats of polish. My toes appear to be burned. I am not sure how to treat safely. I returned to the pedicure shop today to ask if they had encountered this problem before. Of course they said no.
What is safe to use? Three of the blisters have drained already.
