Right I am not 100% sure why stitches start and may well be corrected on this but I believe it is from lack of oxygen to the muscle in question!!!
Causes :-
Closing your chest in by Haunching your body up (tensing) which reduces the area of the lungs, so decreases the amount of oxygen intake so not enough oxygen is getting into your system.
Eating too soon/ too much before running.
How to get rid/ prevention
Relax when running. Run 'tall' dont haunch your shoulders up. If you feel yourself gettinmg a stitch, put your shoulders back and run straight, this will open your lungs up and get more oxygen into your system.
While doing that, breath in for a count of 3 and out for a count of 3, as you may well be shortening your breathing while runningm, and not getting enough oxygen into your system!!!
If you feel you are running tensed up, try holding your thumb and your middle finger lightly together, this relax's your shoulders etc and, please dont as my why, but it does work!!! (I found this out the other week, and tried it at 2 races and both it has helped :) :) )
Eating :-
It is all personal to each runner so :-
Have a diary of what you eat and how long before a run you eat it and if you get a stitch.
Rule of thumb is eat at least 2 hours before running.
I ue this rule of thumb, and if I am hungry just before I will eat a banana, as this is something you can east while running.
The only thing I can think of if it lasts a few days, it isnt the asctual stitch that lasts, its the fact the stitch was so bad, and the muscles had been 'contracting' (I dont know if contracting is the right analogy) then you have the equivalent of a 'pulled muscle' inside your body and takes a few days to calm down.
Hope that helps.
If you dont understand something then ask, and I will explain, if none of these work then feel free to contact me again.
And of course if you are worried at all, please consult your doctor!!!!
