Hello all ~
An update following my ENT appointment. All clear. The tingling feeling I get is in relation to blood rushing to vein at the tip of my tongue. Sometimes it will engorge with more blood, causing a swelling, or in this case a "lump." The doc said I've probably have had these more than I realize & to expect that it will happen again, but there's nothing to worry about. Thanks for the support & best wishes to all.
