Bump on Finger
A localized swelling anywhere in the finger can be referred to as a bump on finger. Finger lumps can be caused by several conditions. These can include inflammation, infections, tumours and trauma. A person may be affected with a single lump on the finger or multiple lumps on the finger. Whatever, the case may be, it is necessary to seek medical attention, if the bump does not subside within few days. Timely detection and treatment will prevent the bump or bumps from becoming aggravated.
What is a Lump in the Joint of the Finger?
Most often when you feel a lump in finger joint that is similar to a balloon, filled with a clear fluid it is a ganglion cyst. Ganglion cysts can be very painful, but are harmless. They may appear for no apparent cause and may disappear on their own. However, most often ganglion cysts form when synovial fluid that lubricates the hands and tendons leak out. When the fluid leaks, it cannot be easily absorbed into the skin. This causes the fluid to harden and thicken, hence the lump in finger joint. A ganglion cyst should never be ruptured with a pin or any other instrument. Most often non-steroidal anti-inflammatory medication will be helpful in reducing the cyst. If such a cyst is causing discomfort it can be aspirated or drained by a medical practitioner.
Can it be due to Arthritis?
Another reason for a bump on finger or bump on knuckle joint is due to osteoarthritis. Osteoarthritis is a common type of arthritis that usually affects the hands. A bump due to osteoarthritis is referred to as a Heberden’s node. If it is due to rheumatoid arthritis it is referred to as Bouchard’s node. Bouchard’s nodes are associated with severe, long-standing arthritis. Whatever the name, inflamed joints can be very painful. Gout too can cause inflammation of the fingers resulting in bumps or bump on knuckle joint.
What is Dyshidrosis?
Dyshidrosis is a type of eczema that causes small blisters to appear on the hands and feet. If you have small, blisters on the tips of your fingers and palms that are filled with fluid that cause intense itching, you could be having dyshidrosis. These blisters may last for about two to three weeks and may disappear on their own. However, if the rash does not go away, you should obtain medical treatment. Large blisters may cause severe pain and will hamper day to day activities. The cause of dyshidrosis is not known. However, stress and seasonal allergies have been known to cause this skin condition.
What is Enchondroma?
This is a benign cartilage tumour that develops on the inside of the bone. They are very common in the small bones of the hands. Enchondroma may weaken the bones which may cause a pathologic fracture. The cause of Enchondroma is unknown. Enchondroma, very rarely becomes a cancerous condition.
What can Cause Small, Red Bumps on Fingers?
Any number of reasons can be associated with small, red bumps on fingers. For example, allergic reactions, insect bites, and fungal infections are all responsible for red bumps on fingers. In addition, certain bacterial infections such as folliculitis and warts that occur due to viral infections are also common causes of bumps on fingers. Bumps on fingers can also be due to more serious conditions such as scabies and syphilis. This will require prescription medication to relieve the symptoms associated with these conditions.
A bump on finger will rarely be due to cancer. This is due to the fact that cancer rarely develops on the hands and feet. However, sometimes sarcomas can occur due to bone abnormalities of the hand. Whether or not cancer is a possibility, it is always beneficial to seek medical attention if you see a bump on the finger or on the joints. This will help diagnose the real cause that is lending to bumps on fingers and treat it appropriately and promptly.
