Re: Shoulder Injuries
What is more important to you, your shodan test on a specific day, or your long term physical well being? Over training with injuries is probably not the best way to go. Cramming before an exam rarely makes much difference. You most likely know all you need to to take your test, so relax a little, give you body a rest. Shoulders are notorious for taking a long time to heal, that's just life.
Mental anxiety leading up to a test can make physical problems worse. You may find that after you have successfully completed your test, the relief will speed up the recovery.
Good luck if you decide to take your test, but if you can't take it on the day, it will come round again.
