Resilient, it sounds like your doctor is not very understanding. Is this a family practice doctor or a gynecologist or someone who commonly treats STIs? Having a caregiver who treats you with the respect you deserve and actually listens to you and treats you as a patient and not the disease you have is the best care you can get.
You might want to ask your doctor if you're a candidate for something commonly known as "magic mouthwash." There are several different combinations of it, and they usually contain some form of anesthetic (numbing medicine) and something like Maalox or Mylanta, and sometimes Benadryl. This is a mouthwash you can swish and swallow several times a day. I've never taken it myself, but as a nurse, I've heard many reports that it is really good for calming mouth and throat pain from a variety of infections. Since I can't prescribe medications and don't know much more about magic mouthwash than what I described above, it's really important you ask your doctor and a pharmacist. If you feel your doctor isn't treating you correctly, go see another doctor or nurse practitioner or physician's assistant (all licensed and trained to treat patients and prescribe medications) and ask a pharmacist her or his opinion on medications to treat the disease.
One of the best things you can do for yourself is to be an informed patient. When you see your doctor, go in with reliable information, such as contained on ASHA's website, and offer your suggestions for your own treatment. YOU are in control of your treatment, not your doctor. I've found that many doctors don't like these kind of patients because they take more time and because they have a certain way of doing things and don't like to change their routine. The more patients they see in a day, the more money they make. As a patient myself, I don't care. I want my caregivers to give me the best treatment, and in order for that to happen, I come in prepared to be an active participant in my care.
Good luck, Resilient. Like your name says, you are resilient and you do have the power to calm the infections. Just stay educated and involved in your care and insist on receiving the right treatments.
