I am 21 and i am not the fittest person ever, but i am not awful, i have recently started running again (as the weather is nicer) and i have found that after a shorter and shorter length i time i start to get a stabbing pain in the right side abdomen area, once i stop running then the pain stops but as soon as i start again it comes back. I am easing myself back into running quite slowing i don't run too fast but the pain is really starting to get annoying. It doesn't feel like a stitch as i can normally run through them without much trouble but this new pain means i have to stop, i think if i carried on through it i may fall over :s. Any help or ideas as to what this could be would be greatly appreciated.
