<s>[INST] My left tonsil seems like it is irritated and my left ear feels like it has some pressure. I don t have a sore throat and only happens when I drink or use smokeless tobacco... it comes and it goes. usually goes away in a few days but seems a little worse this time... i have only used smokeless tobacco for 2 and 1/2 years off and on.. not really consistently. I have allergies pretty bad but i kinda of take things overboard and always think its cancer ... [/INST] Hello Throat irritation is often associated with ear symptoms - like fullness or pressure.  There is tube connecting the two - Eustachian tube - middle ear to oropharynx (throat).  The tonsil irritation could be from infection (virus, bacteria, sometimes a fungus) or allergy or even mechanical - from food and so on.  Post nasal Chat Doctor.  Tobacco in ANY FORM is bad.  Only the effects of additives like tar and so on are avoided by the the so-called smokeless tobacco.  You seem to be intelligent and informed / partially motivated-you MUST try and stop the tobacco It doesn't sound like cancer now - but one is never sure - see you doctor - anything suspicious should be biopsied (sample for analysis)Take care Good luck </s>
