Hello and welcome,
First, I would suggest that you avoid taking your father into the exam room with you if you are uncomfortable with him being there. The doctor's office staff will ask him to wait in the waiting room if you tell them that you don't want him to go in with you.
Secondly, you really do need to talk to the new PM doctor as soon as possible to let him/her know that you shouldn't be taking tylenol and about the hep C. Are you currently under treatment for that with another doctor? If so, you need to let both doctors know that you are being treated by the other so that they can coordinate what meds would work best for you with your medical problems.
It sounds like you already have a particular medication in mind that you are hoping that they will prescribe? If that is the case, I hope that you will keep your mind open to trying other means to help control the pain as well since the doctor may not want to prescribe certain medications for you , for various reasons. The hydrocodone isn't providing any relief at all?
Usually most pain meds will provide some level of relief, even if it is not exactly what we feel it should be. There are also many other ways to help bring pain levels down - ice, heat, excercise, physical therapy, heating pads and heat wraps, topical medications like Aspercreme and Icy hot also help alot to relieve muscle tension and some pain as well, injections into the injured area with steroids also often help relieve pain, and accupuncture as just some of the many other options available to you. Keep your mind open to trying these other possibilities, you might be pleasantly surprised at how much relief you may get from trying these as well as pain medications.
The doctor will prescribe what he or she feels are the best options in medications for you, given your medical history and current physical problems.
Have you had any testing done yet to determine what is causing the pain? He may prescribe physical therapy, or xrays, MRI's , CT scans, emgs to test nerve function as well.
There are also nerve pain medications that are commonly used to treat pain caused by damage to the nerves, which are not narcotics but are really effective at treating that type of pain, which doesn't usually respond well to opiate drug therapy anyway. They also commonly use anti depressants since many of those also have the added benefit of easing nerve pain really effectively.
Anyway, good luck, I'm sure that the doctor will do what ever he/she feels is the best when it comes to treating your pain. I hope that you feel much better soon.
