I am probably re-aggrivating it every so often.. but my index finger has been swollen for about a month now and I can not remember injuring it. I play basketball so I may have sprained it without knowing. It hurt one morning out of nowhere, then one the second or third day became swollen and has been swollen ever since. Can't bend it all the way and hurts a little to straighten it out. What kind of a doctor should I see for this... seeing as I don't have a regular doctor... and a type of doctor health insurance would cover.
