When I had what I think was mild/moderate shin splints last year I too had them in my left leg mainly with my right leg suffering just a little bit less.
Only thing I could do was rest and hope for the best, reduce speed when I did start running again and then being careful with any increase in distance. Pretty sure mine were caused by wearing unsuitable shoes that were a little too big and a particular hill session that I did.
There would also be times as well where I thought they were gone and then all of a sudden they'd just start again, it really is a case of when you think there ok rest a little more and then try again.
Hopefully they'll clear up in good time but mine (even though only mild/moderate) took a good few months for me to be confident they were gone.
