thanks for your responses, girls. I used the inserts and they helped a fair bit, the pain in my calf has lessened but it isn't completely gone. My ankle is certainly a lot better, I still get the pains on top of my foot though.

I don't really know what to do from here. I've never heard of Bikram Yoga, is it popular? I don't have my own transport atm so anything that requires me to go somewhere is problematic

hoobley - i'm lucky, my GP doesn't have any antics about my weight, i don't think he sees it as a problem. I'm going to ask for a referral to a physio and perhaps a podiatrist as well. I used to see a podatrist for this problem when I was a kid (they did xrays of my foot and not my hip, even though they knew my hip was the real problem?), but it didn't exactly help.
