<s>[INST] HiI have just woken up, and noticed that a lymph node on the right side of my neck is swollen. A week or so ago, I had a swollen one just behind my ear, on the same side if I remember correctly My tonsils were giving me some trouble a few months ago, and I had anti-biotics to rid my infection, perhaps it is coming back? My dentist recommended that I had my tonsils removed quite some time ago, but another dentist I visited said that he would only consider removing them if I had persistent problems with them.So perhaps the swollen lymph node is something to do with this. I m 20 years of age, my diet has been somewhat poor the last couple of weeks, but otherwise I would say I am quite healthy in general.Thank you. [/INST] Hi..Welcome to HEALTHCARE MAGIC..I have gone through your query and can understand your concerns..As per your complain in case if you have a recent history of throat infection and even if it is coming back also presently then there is a possibility that the swollen lymph nodes are due to Reactionary Lymphadinitis and it is not a serious condition and when you will take medication for treating the infection like antibiotics the swollen lymph nodes will resolve gradually..You should consult an Otolaryngologist and get evaluated and get tested for bacterial infection [ rapid strep test] and viral infection [ rapid mono test] to rule out the exact cause of infection and treatment can be planned accordingly..If there are recurring episodes of the same then Tonsillectomy will only provide permanent relief..As of now do alternate warm and cool compresses over the lymph nodes..Hope this information helps..Thanks and regards.Dr. Honey Nandwani Arora. </s>
