I think I've got this but I'm not sure. It started last weekend when my glands swelled up. They've gone down now but it's like a clicking in my Adam's apple when I swallow. It's at the front and mostly on the right hand side however it's happening a bit in the centre and left side now. It doesn't affect my eating or anything just uncomfortable. When I've been less stressed I sometimes dont notice it or it goes away. I've read somewhere it can be due to tight, tense muscles in the neck.
