I recently got back from walking the North Norfolk coast, I was walking with about 60 pounds in my bergen and was wearing lowas. About 33 miles in (21 miles first day, 12ish into the next) my left heel started hurting like buggery. I loosened my boots which had been pretty tight as my feet were starting to suffer (no real tabbing style stuff done for about 8 months) and it helped a bit, but I still had to walk another 4 miles that day on shingle and then 10 the next day on it. Since getting home my ankle is painful, especially driving (clutch) and going downstairs. I can also feel a grating, as if my tendon is catching or almost ripping... it's a strange sensation. Does anyone have any idea what I've done and how long it'll take to repair? Any strategies for getting it sorted sharpish as I'm hoping to walk dartmoor in just over a week? Thanks in advance for any information received.
