I fell on my index finger when playing basketball. The area on the palm below it hurt really bad at the time and I went for an xray but nothing was wrong with the bones. The pain subsided after a week and had been palatable for three months now except when I did something vigorous with it, so I thought it was healing. But I hit the same finger again and now the pain is back. Since the problem is not with my phalanges I want to know what other possible reasons, maybe blood vessels, nerves or whatever could be causing the pain. Thank you
