I have had a white nodule seems to be protruding out of my tonsil . it didn't seem to hurt to swallow but did hurt if i touched the side of my throat but now feels as if there is something in my throat . should i be worried ?

No, a tonsil stone: is a benign accumulation of bacteria and debris that can form in a crypt (groove) of a person's tonsil(s). Alhough this problem may cause discomfort, it is not dangerous and is usually easily treatable. A tonsil stone can sometimes be removed by gargling with salt water, or brushing the tonsil with a tooth brush. If these measures don't work, consider seeing an ear, nose and throat (ENT) doctor

Tonsilith...: a sign that your tonsil(s) is/are working very hard to rid you of a harmful invader. Tonsil(s) may be enlarged and or tender. Get plenty of rest, drink plenty of water and eat a healthy nutritious diet. Should clear up in a few days. If very annoying (and they do smell very bad) try removing them by rubbing with a stiff object such as a cotton tip applicator.
