I have been running/jogging the last month, I have been doing really well. I lost 13 lbs so far by watching what I eat and working out. Mostly working out. Tonight I went out for a run, normally I go for about an hour and tonight I made it 35 mins. I had the worst pain in my calves! What is going on?? I hope it goes away! Let me know if anyone else has experienced this and how long it takes to go away. And if I should just drive on and forget about the pain?
