Yes, swollen glands are a very common and normal response to a sore throat. In the UK, these glands are more accurately called lymph nodes. They act as the command centres for your immune system, housing the white blood cells that fight off infections. When you have a sore throat, viruses or bacteria enter the tissues of the neck, and the nearby lymph nodes immediately begin to produce more immune cells to neutralise the threat. This increase in activity causes the nodes to physically expand, which is why you can often feel tender, pea sized lumps under your jaw or along the sides of your neck.
While it can be uncomfortable to feel these lumps, their presence is actually a positive sign that your body immune system is working correctly. Most people in the UK will experience swollen glands during a bout of tonsillitis, a cold, or the flu. These nodes typically return to their normal size shortly after the throat infection has cleared, though in some cases, they can remain slightly palpable for a few weeks.

Why glands swell during an infection
The human body has hundreds of lymph nodes, but the ones in the neck are the first responders for any infection in the mouth, throat, or ears. When a pathogen is detected, the lymph nodes trap the virus or bacteria and begin an intensive process of filtering the lymphatic fluid.
This process involves:
- Cellular proliferation: Rapidly creating new lymphocytes to attack the infection.
- Inflammatory signalling: Releasing chemicals that increase blood flow to the area.
- Fluid accumulation: The node may fill with more fluid as it works to flush out waste products.
In the UK, these are known as reactive lymph nodes. They are usually tender to the touch, which is a key sign that the swelling is due to an active immune response rather than a more chronic issue.
Where to feel for swollen glands
Common locations include:
- Submandibular nodes: Located just under the jawline on either side.
- Cervical nodes: Found in a chain along the large muscles on the sides of the neck.
- Submental nodes: Located directly under the chin.
- Post auricular nodes: Found just behind the ears, often involved if the infection affects the Eustachian tubes.
When to seek a medical review
While swelling is normal during a sore throat, there are specific characteristics that UK clinicians look for to rule out more serious issues. A normal reactive gland should be soft or rubbery, mobile when you push it, and tender.
You should book a GP appointment if:
- Persistence: The gland remains swollen for more than three to four weeks after the infection is gone.
- Texture: The lump feels very hard, fixed in place, or painless.
- Size: The gland is rapidly increasing in size or is larger than two centimetres.
- Systemic signs: You have unexplained weight loss or heavy night sweats.
- Location: You feel a swollen lump just above your collarbone, as this is less common with simple throat infections.
Comparison: Reactive Nodes vs Concerning Lumps
| Feature | Reactive Lymph Node (Normal) | Concerning Lump (Requires Review) |
| Pain Level | Usually tender or painful to touch | Often painless |
| Consistency | Soft, rubbery, or squishy | Hard, stony, or irregular |
| Mobility | Moves easily under the skin | Fixed to the underlying tissue |
| Duration | Resolves within 2 to 4 weeks | Persists or continues to grow |
| Skin Appearance | May be slightly red or warm | Skin may look normal or puckered |
| Associated Signs | Sore throat, cough, or fever | Night sweats or weight loss |
To Summarise
Swollen glands are a standard and expected part of having a sore throat in the UK. They represent your immune system in action, filtering out pathogens and building up your defences. In the vast majority of cases, these lumps are reactive and will disappear on their own as you recover from your viral or bacterial illness. By understanding the difference between a normal reactive node and a lump that requires further investigation, you can monitor your health with confidence and know exactly when it is time to seek professional UK medical advice.
If you have a lump in your neck that has not gone away several weeks after your sore throat has healed, book a review with your GP for a physical examination.
How long do glands stay swollen after a sore throat?
In the UK, it is common for glands to stay slightly enlarged for two to three weeks after you feel better. If they are still present after a month, it is worth having them checked by a GP.
Can I have swollen glands on only one side?
Yes. If your infection is more severe on one side of your throat, such as with a one sided tonsillitis, the glands on that side will often be larger and more tender.
Do I need antibiotics for swollen glands?
No. Swollen glands are a symptom, not a disease. If the underlying cause is a virus, antibiotics will not help the glands go down. They will only be prescribed if your GP confirms a bacterial infection like strep throat.
Is it normal for the glands to be visible through the skin?
In some people, especially those who are leaner or in children, swollen glands can be clearly visible. As long as they are tender and following the typical recovery timeline, this is usually not a cause for concern.
Why are my glands tender even when I don t have a sore throat?
Sometimes glands can react to very minor issues, like a small mouth ulcer or a scalp irritation, even if you do not feel generally unwell.
What is the best way to monitor swollen glands?
It is recommended to take a light touch approach. Avoid constantly prodding or squeezing the glands, as this can cause further irritation and make them stay swollen for longer. Check them once every few days to monitor their size and tenderness.
