Hello, I have had a lump on my gum for over a month now. I changes in colour and in size all the time. Recently it seems like it has remained a particular size but in different colours. I saw my doctor about it lastweek and it was so small then that my doctor told me it was nothing. Recently too, i have been having a feeling that something is stuck in my throat. Although there are no pains swallowing, i feel some discomfort after eating that the food is still stock there. The doctor also told me its nothing. But i am still kinda scared.
