Swollen glands are not necessarily a cause for concern. Glands in the neck and armpits will often flare up if you are fighting an infection and they may become very sore or tender to the touch. These are some reasons why your glands may swell up:
- A tooth abscess or recent dental work. The glands in your neck can often be affected by things that are going on in your mouth. If there is a problem, like an infection, this can cause the glands to swell. Look after your oral health in order to stay healthy.
- A cold or another virus. A virus will trigger your body’s immune system into action and your glands will swell up as your body fights it with white blood cells.
- Something more serious. Very occasionally, it could be the sign of a more serious condition. If your glands do not go back down, talk to a doctor.
