I've been a runner almost my whole life. Back when I was in school, I was a sprinter. After graduating, I took up some longer running for exercise purposes. Running 3-5 miles a few times a weeks. I fell off exercise after starting my career and having a minor injury that took my out of commission for a few months.
Now getting back into it, my shins and the bottom of my feet get this intense cramping/burning like 5 minutes into my run. After I stop it intensifies even more then eventually calms down. Now I'm not running at a fast pace whatsoever. I also do sprint intervals on the treadmill and have no issues besides some pain on the bottom of my feet but very tolerable.
They don't feel like shin splints as I had those in college and they felt very different. I thought it might be my shoes so I got a gait evaluation, which showed my foot curves inward when I run and I got a shoe that improves it. Still no relief. I have a feeling I need to stretch a lot more as I also have patellafemoral syndrome, which is improved by stretching.
Any recommendations for me? Specific stretches?
