Hot spots on outside of foot

The last couple of rides/runs I have had a hot spot on the outside of my right foot. It is on the outside of my left foot as well, but not nearly as bad.

I seem to remember it coming on after a VO2max trainer ride that I did. The following weekend I did a 6 mile run followed by a 10 miler the next day. The foot doesn't hurt worse on the runs, but I can definitely feel the soreness. I did another 60 mile ride this weekend and by the end of the ride my right foot was so sore that the last couple of miles were pretty brutal. The day after this ride I did another 10 mile run and didn't have any foot issues. A relative of mine, who is an RN, said that it might be a stress fracture, but I am not very convinced of that as I think the impact of running would aggravate a stress fracture pretty bad.

The pain basically is noticeable if I supinate my foot and I start to feel it when it rolls over onto the wide spot in my foot (maybe a little behind the widest spot.

I am a month out from my HIM, so I highly doubt I am going to take any time off as it doesn't necessarily seem to be getting worse. Just looking for advice on how to maybe alleviate it somewhat. The only other thing I can think of that correlates with the pain is that I just got a quarq which changed me from 175 to 170mm cranks and the cranks were also changed from what I had on my bike previously. What are the chances that the new crank set will require a different cleat position? I did get hot spots here when I first started riding, but they had since gone away and I have done multiple 80+ mile rides with no pain.

I also tried rolling on a frozen water bottle and that didn't seem to do much for the pain. The pain would subside for a bit, but I think it was more that my foot would go numb while on the ice and then the pain would come back after 10-15 minutes of the foot warming up.
