Bruise First Aid – Introduction
This section provides clear and practical information on Bruise First Aid for people in Canada. It focuses on simple steps you can take at home to manage bruises safely and prevent complications. This guidance is meant for first aid and prevention only, not as a substitute for full medical training or professional care.
A bruise happens when small blood vessels under the skin break after an injury, causing discoloration and tenderness. Most bruises heal on their own without serious problems. However, knowing what to do and what to avoid can help reduce pain and swelling and support faster recovery.

Bruise First Aid – Recognizing symptoms and danger signs
Bruise First Aid starts with understanding the symptoms and knowing When to seek help. Bruises usually appear as discoloured skin caused by small blood vessels breaking under the surface. They often cause mild pain and swelling.
Mild symptoms
- Skin discolouration ranging from red to purple or blue
- Mild tenderness or soreness around the area
- Minor swelling that improves within a few days
These symptoms can often be managed safely at home with rest, ice, compression, and elevation.
Moderate symptoms
- Increased pain or swelling lasting more than a few days
- Bruising that spreads or becomes larger
- Difficulty moving the affected limb or joint
If you notice these signs, monitor the bruise closely and consider visiting urgent care if symptoms worsen or do not improve.
Severe symptoms and red flags
- Severe pain that does not improve with home care
- Bruising after a serious injury, such as a fall or car accident
- Swelling that causes numbness, weakness, or loss of movement
- Signs of infection, including warmth, redness, or pus
- Bruising on the head, neck, chest, or abdomen
- Repeated unexplained bruising or bleeding
If any of these occur, call 911 or go to the emergency department immediately. Prompt medical attention can prevent complications and ensure proper treatment.
Bruise First Aid – Immediate first aid steps
When dealing with a bruise, quick and careful action can help reduce pain and swelling. These immediate first aid steps are safe to perform at home or in the community while waiting for further help if needed.
What you can do right away
- Rest: Stop any activity that caused the bruise to prevent further injury.
- Ice: Apply a cold pack or a clean cloth filled with ice to the bruised area for 15 to 20 minutes every hour. This helps reduce swelling and discomfort. Do not apply ice directly to the skin.
- Compression: Lightly wrap the area with an elastic bandage if swelling is present, but avoid wrapping too tightly as this can cause more harm.
- Elevation: Raise the bruised limb above heart level if possible to decrease swelling.
What to avoid
- Do not massage or rub the bruise, as this may increase bleeding under the skin.
- Avoid applying heat or hot packs during the first 48 hours, as heat can worsen swelling.
- Do not take aspirin for pain relief, as it can increase bleeding. Use acetaminophen instead if needed.
When to seek urgent care
Call 911 or go to the emergency department if the bruise is accompanied by:
- Severe pain that does not improve with home care
- Swelling that rapidly worsens or spreads
- Signs of infection such as redness, warmth, or pus
- Difficulty moving the affected limb
- Bruising after a head injury or if you have a bleeding disorder
These steps provide safe and practical bruise first aid while waiting for professional care if needed.
Bruise First Aid – What NOT to do
When providing bruise first aid, certain actions can make the injury worse or delay healing. Avoid these common mistakes to keep the bruise from becoming more painful or serious.
Do NOT apply heat immediately
Applying heat, such as hot packs or warm compresses, right after the injury can increase swelling and bleeding under the skin. Instead, use cold therapy during the first 24 to 48 hours.
Do NOT massage or rub the bruise
Rubbing the bruised area can cause more tissue damage and increase bleeding. Keep the area still and avoid unnecessary pressure.
Do NOT ignore severe symptoms
Call 911 or go to the emergency department if the bruise is accompanied by:
- Severe pain that does not improve
- Swelling that rapidly worsens
- Signs of infection, such as redness, warmth, or pus
- Difficulty moving the affected limb
- Bruising after a head injury or if you have a bleeding disorder
Do NOT use medications without advice
Avoid taking blood-thinning medications like aspirin unless a healthcare provider recommends them. These can increase bleeding and worsen the bruise.
By steering clear of these unsafe practices, you help ensure proper healing and reduce complications when managing bruise first aid at home.
