You should most definitely consult a doctor about what could be best... But for the time being, if you don't already... do calf raises like crazy, stretch you foot/heel before getting out of bed... I like to roll my foot over a ball after long days when it's starting to get iffy. Hurts like a bitch, but helps relieve pain afterwards. Point and flex your toes, towel stretch, achilles stretch... stretch the shit out of that area, it'll help. But definitely still see a doctor if it's that bad.
