How is groin pain or swelling treated?
Treatment depends on the cause of your groin pain or swelling. Non-emergency management may include rest, changes to your activity or other treatments. It may take several weeks for the pain, swelling or injury to improve.
Self-care at home (for non-emergency groin pain)
Self-care will depend on the cause of your groin pain or swelling.
Here are some tips to help relieve symptoms caused by a groin injury:
- If you are experiencing significant pain, you should avoid bending and lifting things until you see your doctor.
- Try not to wear tight clothing around the painful or swollen area.
- You can use an ice pack to help ease discomfort and relieve swelling in some cases.
- If your symptoms are caused by physical activity or injury, avoid activities that make your pain worse.
- See your doctor or pharmacist for advice about pain medicines, if you need them.
Other treatment options
Other treatment options depend on the cause of your groin pain or swelling.
Some conditions don't need surgery and can be managed with physical or exercise-based therapies.

What are the complications of groin pain or swelling?
Some conditions can become serious if not treated, such as:
- a hernia can become trapped or lose its blood supply

- Emergency surgery is needed to treat these complications.
Can groin pain or swelling be prevented?
Some causes of groin pain or swelling, such as injuries related to sport or physical activity, may be prevented. Avoid overuse and maintain muscle strength to help lower your chance of injury. You can visit a physiotherapist for advice.
Not all causes of groin pain or swelling can be prevented. This is because some are caused by underlying medical conditions.
