Don't know what to suggest dude.
You should get it x-rayed and get a professional opinion.

The only other thing I can think of is to give up guitar for a month.
Get yourself a wrist brace and wear it all the time, that way you're constantly reminded that you have a problem with your wrist and won't use it doing other things either. Then a month from now, try easing yourself back into playing... being sure to warm up first before every session.
