I didn't even WANT to... but in step class yesterday I landed funny and have been hobbling for the last 18 hours (yes, even in sleep I hobble). Not sure what I did. Its right below my knee... on my shin. Its a stabbing pain like a shard of something, but I don't know.
It doesn't hurt all the time, but I take it as my body asking for a rest.
If you need more excuses... I am also sick and was up most of the night coughing... Ew!
