I broke my left scaphoid last Nov. The ortho doc told me that if you don't get if fixed within a reasonable time after injury, it will cause you LOTS of problems down the road. The pain may lesson somewhat but you are doing yourself a disservice to not get it fixed.
I broke mine on Nov 7th and had it X-rayed a couple of days later, doc found nothing. It was still hurting 2 mths later, so a different doc X-rayed it and again found nothing, but he referred me to an ortho doc. This guy (wrist expert) X-rayed it from a different angle and immediately found the fracture. He scheduled me for surgery but put me in a cast to keep me from messing up the wrist any further. He said "If it hasn't healed by now on its own, we will have to screw it together."
Well, God was with me (He always is!) because when the surgery started, the doc found the bone had healed back together! He was shocked. Keep in mind that I broke it on Nov 7th and the surgery was Apr 30th. He stitched me up and put on another cast to allow the bone to continue to heal.
My wrist had weakened considerably after all that time so he put me on some physical therapy. I'm not 100% now but I'm much closer than I was.
You may be a few months out from the injury, but it is not too late to fix it. Don't blow it off...if you try to fix it years down the road, the ortho doc said the repair procedure is much more involved and the chances of success are dramatically reduced.
