I'm 4 months out from my takedown and started to run just a little bit too..nothing crazy and same thing happens to me. I wouldnt give up..another poucher I talked to who's not on this forum, same thing. I ran it by my GI he didn't seem alarmed, he explained it as if the running may cause a bit of inflammation. I'm seeing my surgeon for follow up next week and will ask him his thoughts too.
