I've jammed toes a few times in aikido. Once someone fell on my heel while I was in a kneeling position (up on toes)...I thought the first big toe joint was destroyed it hurt so bad. It ended up being a soft tissue injury. I was battling that for months, taking it easy and trying to be careful. In the end what made it feel better (and my sore knee too) is when I was off the mat for three weeks due to the holidays and recovery from surgery (non-aikido related). Now neither the toe or knee hurt...but my muscles sure do as I get back into the swing of things
Tape it and rest it. If you keep stressing it you'll only keep injuring it.
