Hamstring / leg muscle strain

[scrwright]

Whats the best for dealing with one? Unsure if its hamstring, pain from mid back leg up behind my bum cheek. Just restricts movement & I can't sit very well, currently dealing with it with rest and pain killers but it seizes up if I rest up for more than an hour (mornings are a pain in the arse!). Should I be keeping mobile & ignore the pain (MTFU) or rest up?
