Thanks guys! Appreciate the feedback! I should soon find out more as I see my head and neck surgeon in person tomorrow. My radiation doctor who I spoke to on the phone said while concerning, it could be caused by inflammation from the spot on the tongue hit by radiation. I do know that my tongue, as of a few weeks ago and about six weeks post radiation, really became swollen and painful. It wasn't like this post surgery or even immediately post radiation but it's now enlarged to the point where it's pushing against my lower back teeth. So hopefully I can start working on getting that resolved tomorrow too. Oh what a fun journey this whole ride is.
