There is a painless swollen lump on the left side of my neck since the last 3 months. I consulted a doctor 2 months back because at that time I suffered from swollen tonsils as well. There was a big white spot on it. I thought it was strep or tonsillitis, but then there was no pain along with it. My doctor gave me a mono and a strep test and both came back clear. So he couldn’t figure out what it is and sent me back with a course of antibiotics for my tonsillitis. But they were of no use in getting rid of the lump although they were helpful in shrinking my tonsillitis, even if not completely. I also feel that the size of the node has increased a little bit since my last visit to doctor. I even noticed that I have lost at least 10 pounds in the last 2 months without a change in my diet or eating habits. The only relief I have is that the lump is not painful.
