hard swollen lymph nodes at 15?

User Profile
I am 15 years old and have hard swollen lymph nodes in my neck. The dr can't seem to figure out the problem. They thought that I was allergic to gluten and lactose intollerant. Can you give me any advice on what to ask the dr and what kind of tests that they should be doing?

Hi, welcome to the ehealth forum and I am glad to help you.
In general, lymph nodes become swollen when they are active either due to an infection, inflammation, or cancer. Minor infections can lead to the enlargement of lymph nodes in the neck and groin but those less than 1.5 cm and 2 cm respectively in size are insignificant clinically. And these can stay so for many years and these are not of serious concern.
Your doctor would like to examine the lymph nodes by feeling them and characterize their nature, size and consistency and id required order further investigations such as CBC, chest X-ray and fine needle aspiration cytology etc. And the same is not be possible online.
Hope this helps. Take care.
