I attempted to get in a morning walk this morning. This Michigan mid-April weather has been strange with freezing temperatures and snow flurries, so I took to my treadmill. Yet by 0.59 miles into the walk, I was literally in tears as I held myself up by the treadmill’s armrests and stretched my calves. I tried to push forward to at least complete a mile worth of walking but couldn’t even at a slow tempo due to pain searing up my legs. My cheeks were damp as I hobbled off the machine, beating myself up with discouragement. Why was I suffering from these shin splints all of a sudden?
