<s>[INST] I am a 45 year old male. After New Year I had neck pain on th right side of my neck and found a lump at the same time . Over the weeks since I first noticed it, the lump will grow and diminished in size. Just two days ago the lump got bigger, its painful and hot to touch. That made me go to the doctor. I don t have any symptoms associated with it. I don t remember being sick except for colds. I had an ultrasound done showing a 2.5 cm lump. I am scheduled for a CT tomorrow. Im afraid it will be a lymphoma but the lump is the only symptom I have. Please enlighten [/INST] HiThanks for your query.Lymph nodes in lymphoma are usually painless. They are not painful or hot to touch. I think it is most likely due to inflammation secondary to throat infection. A needle aspiration from the lump may confirm the same. A course of antibiotics may also help.Hope this helps.Regards </s>
