TRIGEMINAL NERVE BLOCK
Trigger finger, also known as stenosing tenosynovitis is a condition that affects one or more tendons in the hand. When the tendon becomes swollen and inflamed it causes difficult movement, pain, stiffness and sensation of locking or catching in the affected finger or thumb.
This condition usually affects the thumb, ring or little finger and even though it is more common in the right hand, it may develop in both hands. When the thumb is involved, the condition is called “trigger thumb.”
The causes of Trigger finger are not known, but a few factors can increase the development of this condition. People with medical conditions such as Rheumatoid Arthritis of Diabetes are likely to develop Trigger finger. Forceful use of the hand due to different activities can also result in pain related to Trigger finger.
Trigger finger starts with discomfort at the base of the finger where the finger joints the palm. The patient may feel the area sensitive to pressure or there may be a lump.
Other common symptoms include:
- Limited movement of the fingers
- Catching feeling
In a severe case of Trigger finger, the finger locks and becomes stuck in a bent position.
