I have required this upper back leg pain today after a tempo run.
It is more of a stretching feeling and discomfort feeling than pain.

Also I know this thread is for upper leg but I have a shin problem too.
It is not a continuous problem but when it happens it lasts 27 min into my running then disappears.
Although I try to warm up and do a little stretching I cannot get rid of it and cannot figure out why it is there lets say for 2-3 weeks then go away for a while and come back.
I also use ace shin wrap but it sometimes helps sometimes gives more pain.
I really cannot figure out what is happening , cannot find any logic to it

Any suggestions to how I can treat them and understand the reasons would be much appreciated .

Thank you very much.
