My son had some form of bug bite on the back of his neck.  The doctor gave him a prescription cortisone.  Now, approximately two weeks later, he has two lumps approximately 1 - 2 1/2 inches away from the original bite.  I assume they are enlarged lymph nodes.  How concerned should I be?
Hi, thanks for writing to Chat Doctor and sharing your sons' health concerns! Yes, you are correct; this neck lump is nothing but an enlarged lymph node due to recent inflammation in the surrounding area! This is normal reactive/preventive action of our bodies immunity system towards any infection, agents or insult...! Therefore, this one does not need any treatment as this is expected to disappear within 6-10 weeks but should be monitored! I would further suggest you, if still not convinced, to go for an FNAC /biopsy and ultrasound of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing your son good health.
