hey chuck,
not to sound like a smart ass, but i say take the meds.
i recently had a blocked saliva duct and it took the full 10 days of meds to relieve the pain and swelling. initially i saw a regular MD, afterwards i was able to see a doc who specializes in this stuff and he was glad to see the effects of the medication... he also said he was 99.9% sure that the problem was a blocked duct.
however since i did have oral cancer and completed treatment 2 yrs ago, he also confirmed that i am scheduled to have a head and neck MRI in the very near future... just to be sure.
so i recommend doing the meds, then see a doc again to see if any follow up proceedures are recommended... note that your history is much different than mine, so your doc might not recommend any further medical services.
you might consider taking Acidophilus tables to help your digestion while on antibotics....
good luck,
