Hamstring

So I think I pulled my hamstring on my right leg ... it has been giving me grief for two weeks now and flares up when I kick, and sitting (which I do a lot at work sometimes) is more than a little uncomfortable.  Self diagnosis is not the most reliable method however I did this a couple of years ago and it feels similar.  Hopefully stretching and keeping my kicks at knee height for awhile will let it heal.    This however is messing with the spinning reverse roundhouse kick in my form,  I think trying to get this kick looking good in the form is how I hurt it.  I believe I did not have the footwork correct coming into the kick and was swinging up enthusiastically rather than around with control like it should be done.  Felt a sharp sproing and that may have been the moment of injury.  REALLY need to work on this kick it looks BAD!  will be doing it SLOWLY for awhile.
