I'm a "morbidly obese" guy who recently went from a work-from-home position to a commuting job. Part of my commute includes a half mile walk from the train station to the office building where I am employed.
I have been experiencing a burning sensation that starts at my ankles and works its way up into both lower calf muscle groups as I do this walk. At first I thought it was my body not being acclimated to the change in activity, but it's been going on for four work-weeks of doing this walk back-and-forth, so it's approximately a mile walk every day.
I'm curious to know if any fitness experts here have some ideas as to what the cause might be and some suggestions to prevent it.
I know I'm overweight and I probably should get some new shoes, but wondering about other potential causes and maybe some ideas as to how to prevent it through certain warm-ups (preferably able to be done on a packed subway car.)
