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.
