Hello, Thank you for asking your query at DoctorSpring
A painless enlarging lymph node suggests Malignancy elsewhere in the body.
Malignany anywhere in the body first metastizes to the lymph nodes resulting in an enlarged lymph node. Here are some home remedies for enlarged lymph nodes. Applying a hot compress can help relieve the discomfort, though it should not be so hot as to scald the skin.
I suggest you wait for a week and see if you develop any other symptoms or if the size of the lymph node decreases. Visit a physician after a week or two. He will suggest you to go for FNAC of node.
Hope this helps. Please feel free to ask follow-up question
