I went to see a private sports physio as I thought it wa piriformis, he said it was a tear in my glute!
I am a nurse and work on orthopaedics, I was telling 3 surgeons about my pain the butt and they all said in unison it was the sitting bone.
Katrina, hamstrings are very long, back of the knee was the hamstring for me. You have just over strode and not noticed it at the time.
When I laid on my front I could not bend my heel up to my bum! my hamstring was literally not working. Looking back what I did when I walked I must have over strode. I iced my hamstring, back of the knee and thigh and took naproxen, this was 3 weeks before my 62 mile walk, for the actual event it was fine. Knee pain went and I have been careful since not to overstride. I am starting to think this is all the results from walking, change in muscles you use and stride.
I also got some biofreeze and that worked really well
K9,I am trying to be really good and stretch, on the foam roller I can feel all the lumps in my butt!
I also cant touch my toes so I guess my hamstrings are tight
