Trigger finger is a condition that affects the tendons in your hand, making it difficult for you to bend your finger or your thumb. If your tendon becomes swollen then it can catch something called a tunnel, which runs through the tendon and the sheath. When the problem has progressed to this stage, it can result in a clicking sound or sensation. If you have trigger finger in one hand then you may very well experience it in the other at a later date.
If you don’t treat your condition then you may find that your finger gets stuck in a bent position; however it is entirely possible for it to “pop” right back into a straight position again. After a period of time, you may find that your finger doesn’t bend at all, and this could lead to more difficulties later down the line.
What Causes Trigger Finger?
The cause of trigger finger is unknown, but it is known that the tendons that are in the palm of the hand are kept in place by bands of tissue. These are called ligaments and they are shaped to cover the tendon. There is also a protective “sheath” which lets out a small amount of fluid, keeping the joint and the surrounding muscles lubricated. If you have trigger finger then there is a problem within the tendon and the sheath, and most often, this is because there is swelling or inflammation. This means that the tendon can’t go into the sheath anymore, so instead it bunches up and forms a lump. If the tendon gets caught in the sheath when it is swollen, it can produce a painful click, as mentioned above.
