<s>[INST] I have large red bumps on back of my tongue. Did some research and understand it may be enlrged taste buds. they are red and throat is sore. My left lymph node seems swollen as well. I have no fever or chills. Have no problem eating either. Called Doctor but he isn't working on account of Boston Marathon. Is this contagious? Will it go away on it's own? [/INST] HIWell come to HCMIf the swelling is not hurting, dose not cause any pain or discomfort then just keep this under observation for any changes, if you find any changes then you have to bring it to investigation and fist step would be clinical examination, hope this information helps. </s>
