Ok so to begin . I'm thinking of reliving past glories and joining a local TA unit while I'm still young enough( just) . Slight problem in that I have a slightly bent elbow from previous service. It wont lock completely out and is probably noticeable as a slight dog leg shape . No real pain and no real loss in strength.Hasn't stopped me from doing anything although it does wobble a bit if Im doing missionary and take one arm away. It was x rayed years ago and a nice white crescent was evident at the joint . Also it makes interesting cracking and popping noises . So my questions then , Will it get past a medical ? Is it something that would disqualify me from re-joining ? What actually is it ? Doc said it was wear and tear, but is that arthritis ? medical types your opinions would be greatly appreciated .
