Hi Dr . samuel :) I had a tonsillectomy December 2012 I had a couple of complications that followed Where my throat just wouldn t heal and had to have a further 2 operations in a space of two months in the end they had to join my throat to bk of my tongue wich finally worked and my throat quickly healed after, but ever since then wen I eat I always seem to get blisters on the scar tissue, is that normal. It s not causing any major proplems can just get irritating at time because I feel them with the back of my tongue??
