Stitches, I have tried everything
I've been running since December and one thing that consistently seems to happen during my harder efforts is getting really bad stitches (7-8/10 pain) to the point I can't maintain my desired pace.
I feel like I've tried everything from this very extensive post from /u/CodeBrownPT I've also tried various breathing techniques and I've even gone to the doctor, who told me there was nothing that could be done.
I'm at my wits end. I'll normally get at least two bad stitches that last for a long time (today I had them for about 10k out of 19k) and I try my best to run through them but sometimes the pain is just too much. This also happened about a decade ago too when I was running a little. It's a very frustrating feeling because often I can feel the rest of my body is capable of what I'm asking of it.
For context, my 5k PB is 19:10, aiming for a half marathon time of 90:00, I'm male, in my mid-30s, running most days.
Does anyone have anything else I can try? Anybody similar out there?
