Swollen fingers can make you uncomfortable. When your fingers are swollen, it can be hard to do everyday activities like typing, gripping objects or even holding a cup. Are your swollen fingers making you worried?
It’s common for fingers to get swollen, but it’s important to know what can cause swelling and how to manage it. If you have swelling that doesn’t go away or gets worse, it’s important to get medical advice to rule out more serious conditions.
What causes swollen fingers?
“Your fingers could be swollen for different reasons, from minor lifestyle factors to underlying health issues,” said Elizabeth (Betsy) O'Connor, DO, a family medicine expert with Banner Health.
Common or mild causes
You could have swollen fingers due to:
- Injury or trauma: A sprain, fracture or even a mild bump can lead to swelling in your fingers. If you’ve recently injured your hand, swelling may be a natural response as your body works to heal.
- Heat: When it’s hot outside, your body might retain fluid, especially in your hands and feet. “Hot weather is a common cause of swollen fingers,” Dr. O’Connor said. This swelling usually goes away once the temperature cools.
- Too much salt: When you eat salty foods your body may retain water and your fingers may get swollen.
- Physical activity: “Exercise, especially when your arms are hanging down, can cause your fingers to swell,” Dr. O’Connor said.
Medical conditions
- Arthritis: In osteoarthritis, the wear and tear of cartilage in your joints can cause swelling and pain. Rheumatoid arthritis, an autoimmune condition, causes inflammation in your joints, leading to swelling and stiffness, especially in your hands.
- Carpal tunnel syndrome: With this condition, the median nerve in your wrist gets compressed, which can cause swelling and discomfort in your fingers as well as tingling, numbness or weakness in your hands.
- Infections: A swollen finger that’s also warm, red or painful could be infected. “You could have an infection around the nail, cellulitis, an infection of the finger caused by the herpes virus or infections due to other causes,” Dr. O’Connor said. If you think you might have an infection, it’s important to get medical care quickly.
- Allergic reactions: Swelling may be a reaction to certain foods, insect stings or other allergens. If your fingers are swelling after you’ve been exposed to an allergen, it’s important to monitor your symptoms.
Fluid retention or circulation issues
Swelling in your fingers could be due to fluid retention, which is called edema. This can be caused by pregnancy, heart conditions, kidney or liver problems or hormonal imbalances.
Raynaud’s disease may also cause swollen fingers. This condition affects the blood flow to your hands and feet and can make them swell or turn blue when you are cold or stressed. You may also notice numbness or a tingling sensation in your fingers.
Other causes for swollen fingers
- Hormonal changes: Hormonal fluctuations, especially during pregnancy or menstruation, can make your fingers swell temporarily.
- Medications: “Certain medications, like steroids or blood pressure drugs, may cause swelling as a side effect,” Dr. O’Connor said.
- Autoimmune disorders: Conditions like lupus or scleroderma, which cause the immune system to attack your body’s tissues, can lead to swelling in your fingers and joints.
When should you see a health care provider for swollen fingers?
In many cases, you can treat swollen fingers with simple at-home remedies. Get medical advice for:
- Sudden or severe swelling
- Swelling that lasts for more than a few days or does not improve with rest and self-care
- Swelling plus neurological changes like numbness, tingling or weakness
- Swollen fingers along with pain, fever, discharge, redness or trouble moving your fingers, which could be signs of infection
- Swollen fingers plus chest pain, shortness of breath or swelling in other parts of your body
“Your provider may be able to treat an infection with antibiotics or diagnose other causes of swollen fingers with lab tests or imaging studies,” Dr. O’Connor said.
How can you manage swollen fingers?
If you're dealing with swollen fingers, you can try these strategies at home:
- Rest and elevation: “Rest your hands and try to elevate them above your heart to encourage fluid drainage,” Dr. O’Connor said.
- Ice packs: Apply an ice pack wrapped in a cloth to the swollen area for 15 to 20 minutes a few times a day.
- Compression gloves: Compression gloves or sleeves can help control swelling and support your fingers as you heal.
- Water and diet: Drink plenty of water to help flush out extra fluids and limit the salt in your diet.
- Avoid allergens: Be careful to steer clear of food allergens or insect bites.
It can also help to:
- Exercise: Regular exercise can improve your blood flow and lower the risk of fluid buildup in your hands and feet. Simple hand exercises or stretching can also be helpful.
- Maintain a healthy weight: A healthy body weight puts less pressure on your joints and makes them less likely to become swollen.
- Manage other health conditions: If you have a condition like arthritis or edema, managing it may help reduce swelling in your fingers.
What professional treatment options are available?
If home remedies aren’t enough or the swelling is caused by a medical condition, your health care provider may recommend:
- Medications: Over-the-counter (OTC) anti-inflammatory medications or corticosteroids can help manage pain and swelling.
- Physical therapy: PT can help improve mobility and strengthen the muscles around the joints if swelling is due to arthritis or injury.
- Targeted treatment: If the swelling is due to an infection, you may need antibiotics. For circulation-related issues, medications that improve blood flow may help.
How can you prevent swollen fingers?
You may not always be able to prevent your fingers from getting swollen, but these tips can make them less likely:
- Stay active: Physical activity promotes better blood flow and lowers the risk of fluid buildup.
- Watch your sodium intake: A balanced diet with limited salt can help prevent fluid retention.
- Protect your hands: Use gloves or padding during activities like lifting or exercising to lower your risk of stressing or hurting your hands.
- Manage chronic conditions: Check in with your health care provider to manage conditions like arthritis, heart disease or edema.
- Stay hydrated and stay cool: Your fingers are more likely to swell if you’re dehydrated or overheated.
