Rest it for a few days and see how you go, I am sure it will go with rest.

For next time:

Core work
Stretch
Technique

We all learn the hard way, me included

Cheers buddy, Technique should be pretty spot on as im a qualifed personal trainer, need to get a mirror in the garage to double check though, i do need to stretch more, just worried that it may spark off my old injury.
