I broke my right humerus 2 years ago (long story) 15 months later it was found that the rod was to far up in my shoulder and causing pain second opp replaced rod into correct position but the screws came out 3rd opp to correct that,they are still out slightly which brings me to my question ,can it still be stable when screws are out a little bit ? I have a pulse machine that I was advise to use to heal the bone that I use once a day? why only once a day ? after the 3rd opp I have a nerve problem in my thumb and four finger, both numbness and stinging, hot water feeling,How long would you estimate the recovery time will be now ?
