But once in a while, a big lymph node can be a red flag for a hidden problem. If a lymph node gets really hard, starts growing super fast, or comes with other symptoms like a fever, losing weight, or pain, it might mean there’s a more serious health issue brewing. In these situations, it’s key to see a doctor pronto to figure out what’s causing the swelling.
When to Hit Up the Doctor
If you spot a swollen lymph node in your neck, you’ve got to keep a close eye on it. You should definitely make an appointment with a doctor if any of these things happen:
The swelling sticks around for more than two weeks.
You’ve got an unexplained fever, you’re losing weight without trying, or you’re in pain.
A lymph node is growing at a breakneck speed or feels as hard as a rock.
You notice multiple big lymph nodes popping up in different parts of your body.
