Two weeks out from rads, the mucositis is likely still getting worse. It does get better, but probably not yet.

Hubby had foul tasting mucus and/or saliva for many weeks before it dried up. He used club soda to try to rinse it out. He did lots of rinsing with the baking soda rinse, neutra-sal and club soda (not all at the same time, he would switch off). Taste and swallowing improved about 8 weeks out. Mouth sores were much better then, too.

It's always a good idea to get the docs to take a look just in case something is infected.
