Tendon pain in the palm of the hand, mainly due to the finger flexor tendons in the palm area of the strain, strain injury, such as long-term lifting, lifting heavy objects or maintain a position for too long, will lead to muscle, tendon, ligament strain, strain injury, after a long time will form aseptic inflammation foci, inflammatory metabolites will stimulate the peripheral nerves around the peripheral nerves, there will be a significant pain. In addition, due to strains and strain injuries, it is easy to appear small blood vessel rupture, there is a small amount of blood leakage, which will lead to localized swelling, as well as the gradual formation of inflammatory edema, which will lead to a further increase in pain, in the movement of the finger, will lead to a further increase in pain.
