Oh sweety....here you go again huh??
I'm so sorry you are hurting like that again. Maybe what you need to do is call the doctor and let them know, let them prescribe yet some more meds (I know how you don't like taking them) but they are imparative to help you heal.
In the meantime, how about sucking on some ice chips? heyjoe may be right, it could be thrush

Are you experiencing any of these symptoms of thrush?
Symptoms of thrush in an adult include:
A burning feeling in the mouth and throat (at the start of a thrush infection).
White patches that adhere to the mouth and tongue. The tissue around the patches may be red, raw, and painful. If rubbed (during tooth brushing, for example), the patches and the tissue of the mouth may bleed easily.
A bad taste in the mouth or difficulty tasting foods.
Here are some ideas to help it feel better if it's thrush and even if it's strep they might help you a bit -
Measures can be taken to reduce the discomfort of thrush:
Drink cold liquids, such as water or iced tea, or eat flavored ice treats or frozen juices.
Eat foods that are easy to swallow such as gelatin, ice cream, or custard.
If the patches are painful, try drinking from a straw.
Rinse your mouth several times a day with a warm saltwater rinse. You can make the saltwater mixture with 1 tsp (5 g) of salt in 8 fl oz (0.2 L) of warm water.
I hope you feel better soon my friend. Keeping you in my prayers and sending out healing thoughtst to you!
