I found this for you:
"The throat chakra is definitely related to communication and our ability to express ourselves, and that can be a complex thing, beyond just talking openly. Sometimes we're not speaking what's really on our minds to others, or more importantly, admitting truths to ourselves. This chakra is about living your truth in all ways, so being honest with ourselves and others and living by it facilitate the free flow of energy through the throat space. Relatedly, vishuddha is also associated with hearing, the ears and listening. A lot of people feel uexpressed emotions, especially grief and love, as a lump in the throat. This happens to me from time to time.
You could try gently breathing white light into the space and mentally chanting 'hum', the bij mantra, during meditation to help dissolve any blockage you may be experiencing." -
