Non-arthritis causes of swollen, painful finger joints – Medical News Today

Although arthritis is a common cause of finger swelling, other conditions — such as injuries, preeclampsia, and trauma — can also cause finger swelling, inflammation, and pain.

Finger swelling can happen when inflammation or fluid accumulates in the tissues or joints of one or all of the fingers. A person may lose some mobility and notice that their fingers are stiffer and more tender than usual.

Some other symptoms of hyponatremia include:
