Outer foot pain

Background: I have been alternating running with cross-country skiing this past winter, depending on snow conditions. Now that the snow is gone, I've been running more - up to 12 miles/week, typically 4 miles each session. I typically run 10 minute miles.

I was doing fine until last Tuesday. After returning from my run, the outside of my foot started to hurt. Wednesday, I could walk only with difficulty. Thursday, it felt better, so I decided to go for a bike ride, which didn't bother it at all thanks to the stiff-soled bike shoes. Friday, I rode again and the pain was nearly gone.

Unfortunately Saturday and Sunday the pain has returned and seems to be getting worse, just from walking around the house, gardening, etc.

I'm guessing this is a problem involving the peroneal tendons, just from the location of the pain (between the pinky toe and ankle, radiating slightly up the calf). Any suggestions for recovery that would still allow me to maintain some level of fitness? Just laying off everything doesn't seem to be helping.

The obvious choice is biking, but it's gotten too cold for that again. I would like to run again, but I'm sure it will make the problem worse. BTW, I'm taking Motrin (600 mg twice a day) and trying to keep ice on the foot.

Thanks for any advice you can give.

Thanks for the tip. I had not thought about the elliptical -- that seems like a good idea since it would minimize foot flex and not require me to really stabilize. Swimming isn't an option -- no pool.

The weather here has gone back to hell in a handbasket -- snow again, so biking is definitely out and a gym-based option is definitely in! If I can't get it under control, I'll seek out a PT who can look at the contributing factors.

Thanks!
