Hey there, this a fairly new symptom for me, I have it now and I had it last weekend. It feels like I have a lump or a sore area not exactly in my throat but lower down between the ribs. I haven't had any bad heartburn for a couple of weeks, so I don't think its been cause my that, but I have been terribly constipated for a week now, tho I don't think that's connected. Has anyone else had this?
