Trigger finger is a common condition that results in pain and snapping of the tendons at the base of the finger or thumb. These tendons are like pulleys that attach to the ends of the fingers to allow for finger movement. As the forearm muscle contracts, the tendons pull each finger into a fist. With trigger finger, this mechanism is not smooth and a snapping sensation can be felt, causing pain.
What causes trigger finger to occur?
The cause of trigger finger not clear, and this condition can appear without any particular cause. It is thought to be genetic and often occurs in one or more fingers and at different times in different locations. Trigger finger results from a difference between the size of the tendon and the entrance to the tendon sheath, usually at the base of a particular finger.

Carpal Tunnel Syndrome is a common condition that occurs when the median nerve is compressed at the wrist, resulting in pain, numbness, and tingling of the hand and fingers. The carpal tunnel is a tight area of the wrist that many important tendons and nerves pass through. It has a floor, walls, a ceiling, an entrance, and an exit. The floor and walls of the tunnel are made up of the bones. The ceiling is the transverse carpal ligament. The median nerve runs from the forearm to the hand and directly through the carpal tunnel. This nerve controls some of your hand muscles and also allows sensation of your thumb, index, middle, and half of your ring finger. When this nerve is pressed and squeezed, carpal tunnel syndrome develops.
What are the symptoms of Carpal Tunnel Syndrome?
There are nine tendons that pass through the carpal tunnel and these attach muscles of this area to bones to allow your your thumb and fingers to flex. Each of these tendons has a slippery covering called the synovium. This covering allows the tendons to slide easily as the fingers are moved. When the synovium becomes inflamed or thickened, pressure develops on the median nerve, adversely affecting its function. With a compromised median nerve, there is less blood and nutrients available, leading to numbness, weakness, and pain of the fingers and thumb. These symptoms are considerably worse at night or while driving. (more…)A Guide to Arthritis
What is arthritis?
The word “arthritis” simply means “joint inflammation.” Inflammation involves pain, swelling, and stiffness of the joint area. When arthritis occurs, these symptoms tend to last for a long periods of time or reoccur over time. Arthritis is very common, and most cases of arthritis lead to tissue damage. It has been estimated that as many as 70 million Americans (or one out of three people) have some form of arthritis or joint pain. Arthritis can affect persons of all ages but it is more commonly seen in older adults. (more…)
