Not quite sure what kind of crutches you have picked up, but there are a huge variety of types now, and some much easier to use if you have problems with hands or arms. I'm thinking of one type that is a combination of underarm and forearm crutch (underarm support, but hand grip in a similar position to a standard forearm crutch), but also the ones where your forearm is outstretched (i.e. elbow at approximate right angles) so you take the pressure along your whole forearm rather than wrist or shoulder.
Hope things come right quickly though. I know how difficult it is when you need walking aids like crutches but can't manage them because of arm problems.
