I had some weird things start in my mouth area about three months ago. I had an ulcer on the left side of my tongue grow. It was not like a canker sore but more like just an open sore. After a couple weeks I went to my GP that then sent me to an oral surgeon. He did a biopsy that returned negative. About a month after that I noticed a growth on the left side of my tongue about two inches behinde the initial open sore. So I went back to my GP that then sent me to an ENT. The ENT did a biopsy and that came back negative. About a week after I had that biopsy I started to feel a lump sensation or like something was there in the back of my throat along with a mild sore throat that seems to come and go. I went back to my GP who sent me for a CT scan which came back normal. After the CT scan I went back to my ENT who looked down my throat with a scope. He said he did not see anything wrong. So I went to another ENT for a second opinion and he said he did see some redness just above my vocal cords and some debris on my lingual tonsils. I insisted that a biopsy be done on my lingual tonsils and he said ok after explaining that he did not see anything that really conerned him. Should I go through with this biopsy or are the tests I have had to date enough evidence to conclude my results. I has been two months of this feeling of something in my throat and mild soreness off and on.
