Injured my foot a year ago, skateboarding. I though it was turf toe, from so much extension. Around the same time, I also had some blunt force trauma on the first metatarsal, also while skating. Not sure which injury is most relevant to what came after, or if both are equally complicit.
I used R.I.C.E., and started taping for turf toe when I exercised. I found that skating was too harsh in the short run - the extension was too painful - but I could still run on the foot without issue. The pain actually sets in after running. Particularly when taking public transit home, the vibrations on the bus/metro set my foot on fire.
In the first weeks after the injury, there was some minor bruising and some difficulty weight bearing on the days following exercise. In between it was fine. It continued to flare up until I finally decided "no more." I rested it for approximately 12 weeks. No running, jumping, etc. Only light walking as necessary. I also saw a doctor and physical therapist, and was x-rayed.
The x-ray showed no fracture. The physical therapist noted a marked difference in range of motion between big toes and prescribed some exercises. They definitely helped strengthen my feet.
I went back to exercise - soccer on artificial turf and hard indoor surfaces. The pain came back immediately - not while playing, but again, about 10 minutes after stopping. Some minor soreness on the day after, but by day 2 it's fine.
Once again, the most obvious and interesting symptom to me is that I can run without feeling any discomfort. After running, there is intense pain made worse by vibration.
At one point, I ran barefoot on sand. I was expecting it to flare up, but something seemed to pop or stretch and I actually felt much better afterwards. It was fine for about a week, then reverted to injured status.
I'm considering a carbon fiber or similar insole made for Morton's foot/turf toe, but they are expensive...I'm not sure what other options are there.
