hi Doctor, good day,

Im Nawaf. im 21 years old
i had a left shoulder dislocation on 3/31/2014 while i was swimming.
the doctor told me that i have damaged my ligaments and i have to do an arthroscopic surgery.
so i had an operation on 6/8/2014. the doctor told me that i can start my workout (gym) after 6 months as a beginner. so i started my workout and everything was going well. i never experienced any pain from my shoulder again but on 6/6/2015 i dislocated my shoulder again while i was hanging on a pull up rod and i slipped my right hand and my whole body weight was on the left shoulder so i fell.
after sometime in the same hour i dislocated my shoulder again.
and now im not really comfortable with it coz it pains and i always feel that it will dislocate again and again and i always have muscle catch on the same area. can you please help me out with this.
