Return to swimming after shoulder dislocation

[lostroadrunner]

In October I dislocated my shoulder playing tennis and I had to go to the emergency room to get it put back in. I have a long history of shoulder dislocation but this is the first time I have done it in about 8 years. In November/December I went to Physical Therapy twice a week and responded very well and the shoulder feels a lot stronger now. I was wondering when can I resume swimming training again for triathlons?

Thanks!
