hi,im 26 yrs old,,light smoker,,last month i had a cold with a slight cough,,i had noticed a small lump on my right side of my throat,where my lymph node is, is was tender for awhile,,once my cold and cough went away,,i noticed i still had a slight lump,figured it was due to the coughin,,but a month and a half later i still have the lump but its more swollen and tender now,it hurts when i swallow,i have fever that comes and goes, could it be tonsillitis??
