for those who run-pain in side?

are you having a meal in the 2 hours before you start running?

I've typically heard its a diaphragm thing, need to stretch it out properly. I'll paste some info from an article below, but one method to stop it is to breath deep, hard, and loudly. I know this may be weird if people are around, but doing that will help stretch out your diaphragm and alleviate the pain. Also, start a little slower so you are not taking fast, shallow breaths at the beginning, ease into your run.

Side Stitch Info....
A more complicated explanation put forth by some researchers is that a side stitch is caused by stretching the ligaments that extend from the diaphragm to the internal organs, particularly the liver. The jarring motion of running while breathing in and out stretches these ligaments. Runners tend to exhale every two or four steps. Most people exhale as the left foot hits the ground, but some people exhale when the right foot hits the ground. It is the later group who seem more prone to get side stitches.

Exhaling when the right foot hits the ground causes greater forces on the liver (which is on the right side just below the rib cage). So just as the liver is dropping down the diaphragm raises for the exhalation. It is believed this repeated stretching leads to spasms in the diaphragm.

What to Do for a Side Stitch
If you develop a side stitch when running, stop running and place your hand into the right side of your belly and push up while inhaling and exhaling evenly. As you run or swim, try to take even, deep breaths. The stretched ligament theory would argue that shallow breathing tends to increase the risk of a stitch because the diaphragm is always slightly raised and never lowers far enough to allow the ligaments to relax. When this happens the diaphragm becomes stressed and a spasm or "stitch" is more likely.
Some other ways to alleviate the pain of a side stitch include:

Tips for Preventing a Side Stitch
• Time your pre-race meal to allow it to digest prior to the event
• Avoid drinking reconstituted fruit juices and beverages high in carbohydrate and osmolality before and during exercise
• Stretching may relieve the pain of a stitch. Raise your right arm straight up and lean toward the left. Hold for 30 seconds, release, then stretch the other side.
• Slow down your pace until pain lessens.
• Massage or press on the area with pain. Bend forward to stretch the diaphragm and ease the pain.
• * If you continue to experience pain, see your doctor.

I've had a similar problem ever since I started running and Zumba. I always thought that it was breathing issues, but after spending months in yoga and pilates classes working on my breathing and paying attention while I exercise, I found that my breathing wasn't the issue.

I went to my MD who ended up sending me to a physical therapist. My PT found that my overall body posture was incorrect (I stick my butt out, and my chest forward) which overextends my upper rib cage. It doesn't cause any pain at all when I am not exercising, but as soon as I start to do anything involving jumping or running, I get sharp pains right under my breast, at the top of my ribcage. The pain subsides when I cease exercising.

So, the overall long-term solution is to correct my posture. My PT has me "connecting my pelvis to my sternum" while sit/stand/walk and doing some other exercises to strengthen my deep abdominal muscles. What will happen eventually is that the posture correction will cross over into my jumping/running/exercise habits.

But, if fixing your breathing doesn't work, go to an MD or PT! My MD had no idea what was wrong, short of there being inflammation near my upper rib cage.

So, yeah food within 3 hours of running causes it with me. Also, if I haven't had enough water I get it.

I also experimented with different breathing. A magazine said to try inhaling and exhaling on different feet. I don't know if that helped or it just helped me focus.
