Is this the first time you are feeling this? Or you
occassionally feel this way?
Sufficient rest, water intake, stretching before exercise, start
off too fast etc will cause discomfort. BTW, how long is your run?
Distance, timing(pace), at what stage of the run you are feeling
this?
If you are feeling strange during the run, tried to run slower, or
even do a walk and jog again later when you feel better. 
everyone have some sort of problem with their body(nobody is
perfect), it is knowing it and how to address it, that will put you
in a better position to deal with it and live with it.
