I wouldn't try to dive in MA with that injury because I'd be afraid of reinjuring my arm while putting on my wet (dry) suit. If you were to come to Florida, I'd consider it....
Dude...
Listen to Walter.
Speaking from the age where things that used to not hurt now hurt frequently, just because, give yourself time to heal. There will always be another dive...no need to rush it.
consider some of the ancillary things you could be doing with that time - such as:
* taking some DAN courses, including the O2 provider course and the defibrillator course;
* read everything there is to read about decompression theory and possibly take a course in Advanced Nitrox or beginning Trimix to begin to go over some of the concepts
* buy some spare neck and wrist seals, and some glue and tools, and learn how to repair a blown seal on your own drysuit far from any dive shop
* take a course to learn how to perform basic maintenance on your regs
* take a photography course or underwater videography course with the idea of learning how to edit your own digital footage
* take a tank VIP course and learn how to O2 clean your own steel and aluminum tanks, as well as take apart, perform preventive maintenance on, and O2 clean your own manifolds
* take a First Aid course and Emergency Responder course to learn how to respond to injuries on live-aboard dive boats far from any port or medical facilities
* research trip insurance, medical evacuation from resort destinations, and other trip planning details to use for your next trip to Honduras or wherever.
You get the point.
There are literally hundreds of things you could do during this time that would make you a better diver, when you're able to get back in the water safely.
Trying to dive one-armed and possibly either reinjuring yourself, prolonging your recovery period, or whatever just isn't a wise thing to do when there are so many other interesting alternatives that you can use that time for.
Just my humble opinion,
Best,
Doc
