On Wednesday I jogged 3K and walked 2K alternating jogging and walking. My left shin was a little sore, but I really wasn't too concerned. I've never had shin splints before. Thursday I pushed myself to jog for 5 laps straight around the track (the most I've done in the past is 3 in a row). My left shin was pretty sore for most of the jog, but I figured it would loosen up...eventually. After 5 laps jogging, I did one lap walking and by this point I was in so much pain that I basically limped around the track. I did some stretching afterwards and proceeded to sit down and contemplate whether I could actually make it back up the hill to my apartment (about 1K). My leg was throbbing and shooting random bits of pain from my ankle to my groin. I actually thought I might vomit, just to give you an idea of how much it hurt. I didn't have my cell phone with me to call anyone so I sat and contemplated going inside the Sportsplex and asking to use the phone or just sucking it up and climbing the hill. Because I'm me, which means I'm not a princess, I sucked it up and climbed the hill. After two hours of laying on my couch and attempting to rub out the pain, I was back to a semi-normal feeling in my leg.
Advice from a friend: just push through the shin splints, they'll ease up.
Advice from the Mayo Clinic: know when to rest; at the first sign of shin pain, take a break.
