<human>: Could you distill the essence of the text into 1-3 sentences?

I just recently started running consistently for the past 2 weeks, but during the past 4 runs I have been experiencing a pain in my right abdomen once I start breathing heavy, I noticed it after I ran VERY hard one night, the furthest I have gone. Now the pain eventually forces me to stop, and I usually cant get going again once it's there.

People are telling me it's just because I jumped into it pretty hard and overworked my body, and I hope they're right. I took a rest yesterday, and just went for a run right now, and (I don't want to sound dramatic) but it was a rather sharp pain that forced me to stop today.
