I doubt the Vicodin caused the tongue blisters but it could have triggered the virus that is the cause of tongue blisters (canker sores on the tongue). They can be treated at the dentist office or a general practitioner's office. There is a solution that will help with the pain and treatment of the sores. If you have a dentist just go there and they will probably see you without an appointment since it only takes a few minutes to give you the solution.
