I've been having a swollen arch for more than 2 weeks now. I've been doing some walking and running in those weeks, but nothing that hurts. On the run my arch become swollen (it's pretty much the entire arch), I got shooting pain in my left ankle and had a slight aching in the arch.
I did have some pain yesterday, I walked 4km in sandals to a climbing crag, and the last 500m hurt my ankle and where the arch connect to the heel, but on the way back I walked barefoot the entire way back and I felt nothing of it. I'm thinking it's Plantar Fasciitis - I do have some heel pain in the morning if I don't give it a massage. But I suppose Tarsal Tunnel Syndrome is a possibility as well, because of the ankle pain and swelling of the entire arch (I'm not sure if this happens with PF).
I took some footprints where you can see my right foot has very high arches while my left foot has a more normal height. If I stretch my toes back the Plantar Fascia is also much more visible on my swollen foot - it seems to hang lower. I'm not sure if this is because of some tear in the Plantar Fascia or because of a tear on something that's supposed to pull on the Plantar Fascia. Again, no specific exercises hurt. I think my running form is pretty good, I feel light and relaxed when I run, and I think the injury came of overuse. I don't have ice, but I put my feet in cold water 2-3 times a day.
What I really would like is to get some insight on whether this might be PF or TTS. I know TTS is very rare, and especially in young age (I'm 17 with no previous ankle problems), plus that my ankle really doesn't hurt or ache on a regular basis. My arch really doesn't hurt either, it just feels swollen. I've been thinking of not running until the swelling goes down, because the arch usually do feel more tender/tight if I run regularly. http://img412.imageshack.us/img412/3500/feets.png

Thanks for your time and any replies!
