Last weekend during the North East XC I developed what I thought was a stich. I considered dropping out on the first lap but ran on through in great pain and had to stop 3 times on the last lap to try to massage the stich out. Now I completed the course and expected the pain to go. It's 5days later and the pain is still there under my left ribs. Its uncomfortable to walk down a corridor. I managed a run on Tuesday using a very altered breathing technique (which meant the pain dissappeared) but it's been there during movement since. Have I ripped something? Is this usual? I'm getting quite concerned as I'm running the Rosedale RUmble in 2weekends and would quite like to complete my training/not let my fitness fatigue horribly before then.

Cheers,

Matt
