Clinically, patients with index finger pain are commonly caused by the following conditions: i. Patients who eat animal offal, seafood and other foods containing high purine for a long time can cause a significant increase in uric acid indicators in the body. Large amounts of uric acid deposited in the joints of the extremities can appear as substantial swelling and pain. Patients need to take oral allopurinol to reduce the uric acid indicator in the body, which can improve the painful symptoms of the finger. Second, the local skin of the index finger breaks down, and bacteria enter the tissue interstices along the break, which can cause acute purulent infection, resulting in obvious local swelling and pain. Patients need to perform surgical incision of the skin and subcutaneous tissue as soon as possible to drain the fluid and pus in the interstitial space of the finger. The swelling of the finger can be relieved more quickly after the inflammation is controlled.
