Hi everyone. I am due to run W1 R3 tomorrow and ever since my first run on Monday I have been getting EXTREMELY bad stitches when I’m simply walking to work. I don’t get stitches when I’m running, but any movement on my rest days causes me to get a horrible pain in my right side. Has anyone experienced this, or knows what to do? I have tried breathing in and sharply breathing out and that makes the pain subside for a few seconds but it always comes back.
