Few days ago had a bad sore throat when i awoke. soreness is gone now mostly. but now, lump in throat & swollen tonsils. no pain. pictures on profile.

So you : Had viral or bacterial infection, your lymph nodes reacted to fight infection. Smoking not good.

Cannot see pictures: Viral, fungal, or bacterial infections can cause lymphatic tissue (lymph nodes, tonsils,adenoids, back 1/3 of tongue) to swell as they trap pathogens. See your GP of an ENT as soon as possible to have swollen areas examined.
