Go see a doctor.

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.
go see your doctor i could be infected and if you leave it too long you could have tongue problems :/
TCP is a type of antiseptic that is widely available in the UK and Ireland. Yes, TCP can help fight blisters on your tongue but it must be diluted with water and not swallowed. It is fine to dab diluted TCP on your tongue or to gargle it.
