Lymph nodes - glands that aid the body in fighting infections - exist throughout the body. If you have ever gone to the doctor with a cold or a sore throat, you may remember having your glands checked. During an illness, lymph nodes can swell up and can cause mild pain. They are most noticeable in the neck and behind the ears. Don't be alarmed if you feel these glands and you aren't feeling well. Again, it is usually a sign that your body is fighting off a simple infection. Always see your physician if symptoms persist.
