( first rectify your uric acid level) 4.The criteria for enlarged lymph node is more than 2cm AP (anterior-posterior) measurement. 5.So now take an appointment with your GP and get the underlying problems treated. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? do not hesitate. Thank you.
