Alright, I was fine all the way through boot camp with the Marines, and we ran a lot. Then, 10 days later, I ran once more (3 miles, always) and I did fine. After that, I didn't run for 2 months straight, but I did hike a lot. About 2 minutes into the run, my WHOLE stomach started cramping bad. Every muscle in my stomach started going crazy hurting. Now that i'm home, it has gotten a lot better everytime I run, and it only starts hurting when I get completely out of breath (if I start running at about 90% mhr, or if I just run at a good speed for a long period of time). I drink a lot of water, and I eat a banana with my protein shake every day. Will it just keep getting better, or are there any ways to make it go away faster?
