Arthritis is a common cause of finger swelling. However, other conditions — such as injuries, preeclampsia, and trauma — may also lead to a swollen finger joint.
Finger swelling can happen when inflammation or fluid accumulates in the tissues or joints of one or all of the fingers. A person may lose some mobility and notice that their fingers are stiffer and more tender than usual.
Both minor and more severe infections and conditions can cause varying degrees of swelling in the fingers. If someone experiences finger swelling along with pain, heat, and flushing, they should seek urgent medical advice.
Read on to learn more about some potential causes of finger joint swelling that are not arthritis, accompanying symptoms, and treatment options.
During hot weather, the
Generally, when someone experiences heat edema, their skin is shinier and stretched around the swollen area. They may also feel a tightness in their fingers when picking up cups and other objects.
To reduce heat edema, people should try to move into the shade. They should also ensure that they eat and drink enough during the day.
When a person exercises, they feel hotter. To cool down, the body pushes the blood
However, finger swelling is sometimes a symptom of a more serious condition called hyponatremia. Exercise-related hyponatremia occurs when
The early stages of hyponatremia may present with puffiness and swelling in the hands and feet. According to the National Kidney Foundation, if a person has sudden or severe hyponatremia, they require urgent medical attention.
Some other symptoms of hyponatremia include:
- nausea and vomiting
- restlessness or short temper
- loss of appetite
- muscle spasms, cramps, or weakness
- loss of appetite
- low blood pressure
Finger swelling from exercising usually goes down when a person takes a break or ends their workout.
Treatment for hyponatremia varies depending on how low a person’s blood sodium levels are. Some people may need to stop drinking until they urinate, whereas others may need intravenous (IV) saline.
When blood sodium levels are severely low, some people may need hospital admission for close monitoring and frequent blood work. This is because hyponatremia requires very careful correction. However, if correction occurs too quickly, some people can become sicker, and this can be life threatening.
- vehicle accidents
- catching fingers in machines
- thermal burns
- chemical burns
When a person hurts their hand or fingers, they usually experience pain and swelling and lose finger mobility for a while.
If the damage is particularly severe and causes nerve injury, a person may later develop complex regional pain syndrome (CRPS), which occurs when the body’s inflammatory response to the injury is too high.
Some CRPS symptoms
- changes in skin color and texture
- changes in hair or nail growth
When a person injures their finger, immediate treatment usually includes:
- taking over-the-counter (OTC) anti-inflammatory medications
- taking OTC pain relief medications
- taping the finger to restrict movement
If stiffness develops, the person may need to perform finger exercises and continue to take anti-inflammatory medications. If symptoms do not approve, a person should seek medical attention.
Herpes simplex virus (HSV) is the most common viral infection, whereas Trichophyton, Microsporum, and Epidermophyton species tend to cause most fungal infections.
Depending on where the infection is, a person could experience:
- heat around the swelling
- skin darkening
- loss of finger function
Antibiotics can treat bacterial infections. HSV could resolve on its own, but a doctor may recommend antiviral treatment if it does not. Depending on how severe a fungal infection is, a doctor usually prescribes topical antifungal medications to apply to the affected area before considering oral medication.
A person should speak with a doctor if they experience any symptoms of an infection.
When someone has carpal tunnel syndrome, the median nerve in the wrist is compressed, which causes pain in the hands and fingers. In many cases, people report that their fingers
Some other symptoms of carpal tunnel syndrome include:
- numbness in the index and middle fingers
- tingling during the day and night
- difficulty grasping objects
- avoiding activities that trigger pain
- taking OTC pain relief medications
- trying alternative therapies, such as acupuncture
- undergoing surgery
Bursitis occurs when the bursa inflames. Bursae are small, fluid-filled sacs that sit between bones, tendons, and muscles. Bursitis can develop anywhere in the body, including the fingers, but common areas of inflammation tend to be in the hips, elbows, and knees.
When someone overuses their joints, it can lead to bursitis.
According to the United Kingdom’s National Health Service (NHS), some symptoms of bursitis include:
- tenderness around joint
- reduced joint mobility
- swelling and skin discoloration
Treatment options for non-infectious bursitis in the finger include:
- resting the area
- icing the area
- taking OTC anti-inflammatory and pain relief medications
- taping up the finger to reduce movement
Scleroderma means hard skin. It is an autoimmune condition that affects the skin and underlying connective tissue. It can also sometimes lead to multi-organ involvement.
When a person has this condition, they may notice their skin becoming stiff and swollen around the finger joints.
Some other symptoms of localized scleroderma include:
- changes in skin color on the fingers
- finger joint pain
- taut and shiny skin where there is swelling
- immobile fingers
There is currently
Some swelling in the fingers is normal during pregnancy. However, if swelling occurs rapidly and with other symptoms, a person should contact a doctor immediately.
When a person has preeclampsia, they
- swelling in the fingers, hands, and feet
- a persistent headache
- blurry vision
- difficulty breathing
In severe cases of preeclampsia, the individual may receive IV medication to control their blood pressure and prevent seizures.
Some other potential causes of finger swelling include:
People typically experience pain and swelling in the fingers after a sprain or injury. If the swelling does not show any signs of reducing after a few days, a person should contact a doctor — especially if the area feels hot.
Sometimes, finger swelling may be a symptom of a more serious condition, such as preeclampsia or scleroderma. In these cases, a person usually experiences other symptoms, such as headaches and pale fingers, respectively.
Finger swelling has various causes. Injuries, physical activities, and environmental factors such as hot weather can all cause finger swelling. Some rare autoimmune conditions, such as localized scleroderma, can also present with finger joint swelling.
If a person is pregnant and their fingers swell rapidly, they should contact a doctor to rule out preeclampsia.
