Hi all... i am on week 8 and completed the first run yesterday even completing 5k. today however i have a dull ache on the right hand side of my waist (a bit like a stitch is about to come on) but i've been sat down all morning. it also wasnt there yesteday after my run... any ideas x

Well done for the run and the 5K. I'm not sure what it could be other than maybe a pulled muscle? It's easily down after exercising. If it doesn't go away in a day or two then maybe a trip to the docs would be worthwhile?
