by the way something came to my mind with your message which makes me think...
many months ago I ahd a phase where I felt like there was a kind of lump either in my lump or throat area.I often felt pressure on the front side of my neck,but also at the back side,especially when I took a shower it felt kinda strange...
just mentioned that because I read something about a "lump in the neck feeling" and that reminded me of that.It´s not there at the moment but anyway...
