Smurf!! That's a terrible thing to have to go through. I'm thinking of you and Hank and sending out lots of healing thoughts. As for the laser... we have one where I work, it's not clinically proven but it's also not harmful. Anecdotally I can say that it does seem to facilitate healing in some conditions, fractures being one of them. The inflammation seems to go down faster and range of motion increases more rapidly. But I have also seen it do absolutely nothing for some people. My advice, see how it goes without and if he doesn't continue to improve, think about going back in for another treatment. You should not have to commit to a series of treatments, you should be able to do it as needed.
