So this is happening mostly at night since 2-3 days , that when I swallow I feel pain and lumpish deep in my throat near area where neck ends on left side. Also this doesn't happen during the day , I felt it significantly during the night. Also it's not the sore throat kind of pain or dryness. I had swallowed a very small fishbone and I do remember it scratch my throat, so I am guessing that is the reason. But then it does not pain during the day .
