I have to go see my PCP in a few weeks, I have to ask him to send me for a MRI or a CT scan. I think the Nexium is still working. Come to think of it, I don't think my Dr. check my thyroid gland the last time I was there. He was so busy that day. He had just got a lot of NEW patience's since 2 Dr. in the area had just retired. I'll bring it all up to him in about 3 weeks. I don't think its post nasal drip. This is more like a pain near my larynx.
It could well be that your Nexium isn't working well for you now? Have you had any scans done on your neck? Did the MD you saw check your thyroid gland by palpating it? Please remember that your physician works for you, and if you aren't happy with his/her care of you, it's more than feasible to find one that will care for you properly. If you tried the gargling with warm salt water 4 x day, and it didn't help, it may be that you have post nasal drip and an allergy pill could help. However, I'd rule out other pathology first by requesting a CT or MRI of your neck! Good luck!
Is your temperature high or high-ish. Can be some form of strep throat. Check out this site: http://m.wikihow.com/Tell-if-You-Have-Strep-Throat
