I have just been diagnosed with either a blocked saliva gland/duct or a damaged saliva gland. I have to have some tests later this week, but if it is the latter, apparently I will have to have the gland removed. Has anyone had tests which involve injecting dye into a saliva gland - which sounds painful to me, and/or had a saliva gland removed? If so, how painful is it, how long does discomfort last, and are there any other potential side effects I should ask my doctor about?
