I dealt with this exact same thing - Morton's Neuroma - pain on the pad between the 3rd and 4th toe. I couldn't put any weight on that side of my foot and limped for a good 8 months before I did anything about it. I iced it for a good week - 3-4 times a day, to get down all the inflammation that had been building the months past. I also taped it and that made a huge difference. I could feel the extra support it gave me. Because you are so active, taping would be a good idea to help prevent any further damage. I did a treatment with a wrap called BFST Wrist Wrap. I wrapped this around that area of my foot and within a month and a half I was healed and no more limping. That was a good 7-8 months ago and it hasn't come back since. I got mine from walking barefoot on the beach one day. Felt it that very evening. I'm wish you all the best as I know exactly what you are going through. I put in the website from where i got mine.
