Lump on my tonsils

Dear all, This is the first time I am posting. One month ago I start to feel like something swollen on the upper part of my throat/mouth, I looked with the help of a torch and I discovered a lump (if I can call it this way) on my left tonsil, is like a piece of grown flesh round not sure how to explain. I feel the same part of my throat irritated too (red). I don't cough, my voice has not changed, I did not loose weight and I am feeling pretty fine. I have contacted my doctor to check on it Can someone advise me about what this could be? I am quiet stressed waiting for my consultation. Thank you in advance. ****
