throat cramping up and swallowing issues

Just last night I woke up with the worst cramping pain in my lower throat (not long after I took supplements Vimergy vitamin b12, melatononin, and goldenseal) It felt like my throat kept opening in and out and I couldn't even sleep comfortably. As I went back to sleep, the swelling went down. Even today, I've been experiencing issues swallowing. Could this be related to viral activity, vagus nerve/cranial nerve inflammation, or thryroid issues ?
