Ok I have been working out for a little over a year now and around 6 months into it I hurt my shoulder.(Dont know how)It went away eventually but has came back twice and im currently going through the same dam shoulder injury.The first time it happened I went to the doc and he gave me all sorts of tests and could not find anything noticably wrong.He said it was probably a tear.Well I can work out fine except for chest days.My question is can I continue to train and just go light on chest day? I've missed so many days in the past because of this injury and im starting to think I might need surgery Help!!
