How can you cure stitch?
Concentrating for 10 full breaths (as much in through the nose as possible) has instantly cured 100% of stitch issues I have ever had. It seems to work a treat for people I exercised with and trained too.
Dr Gabe Mirkin has an alternate method:
Side stitches are caused by a stretching of the ligaments that run downward from the diaphragm to hold up the liver.
You can relieve the discomfort by stopping running and pressing your fingers deep into your liver to raise it up toward your diaphragm. At the same time, purse your lips and blow out as hard as you can against the tightly held lips.
Sounds a bit intrusive for my liking, but being a Sports Doctor he is probably more qualified than me to offer advice!
Your liver sits just behind the lower rib cage. You can see a good picture of where it is located in the body here.
Have you had luck with either of these methods?
