<s>[INST] I have a soft lump ON my lower jaw I noticed last week.  It moves around if I touch it. Today it has become increasingly painful to the touch and I am experiencing occasional sharp pains also. I also yesterday developed a sore throat, body aches. And some post nasal drip. Do I need to be concerned about lump?
