Swollen, inflamed toe, blister between fingers, throbbing pain. Treatment options?

My toe (the one next to the pinky) on my right foot is swollen and inflamed. There appears to be a blister (popped already?) in between this toe and the pinky. It s been hurting for a few days now but is far worse today. I play a lot of softball and therefore do a lot of sprinting. Not sure if my turfs were a little too tight. I was able to run well through the pain before but I could not even wear my sneakers this morning. I didn t notice any specific time when I may have injured the toe so it just appears to have gotten progressively worse. It was throbbing last night so bad that I couldn t fall asleep. Ice relieved the pain and allowed me to fall asleep. Any thoughts on the cause of this and what I can do to treat it myself? And prevention in the future?
