Also had severe shoulder injury. I felt the pain in the front upper part of the shoulder (arm) at exactly the same part of the stroke. The problem though actually originated from the shoulder blade (scapula) which can lead to impingement in the shoulder.
So for me treatment looked like this:
* My PT prescribed me some mobility and strengthening exercises for the scapula (which is very important for long-term recovery and prevention)
* Icing didn't help at all (maybe it does for you though, especially in the beginning to fight inflammation, which is not the root problem though. Definitely doesn't hurt). Rolling on a ball around the scapula did work and I had quite some tender spots (https://www.youtube.com/watch?v=5QiUzWE9Z7M)
Those are important I think and are a MUST but what really helped short-term (not short-term as in trying this once and going for a 5k swim afterwards):
* Just hanging from a bar. Not actively pulling yourself up, just hanging passively from a bar. If you can hold it for 30 sec in the beginning, go for 5x30 sec 2 times a day. I got a pull-up bar at home which makes it easy to do in the morning and evening. You can google it, there's quite some research on it. Coincidentally I even heard Joe Rogan and Dan Bilzerian talking about it in a podcast (which doesn't mean anything, I know)
This might very well be the only "body hack" I have ever found to be working for me.
Stay clear of swimming for 2 weeks or so at least before you even try swimming again and if you notice any pain, stop immediately and give it at least 2 weeks again.
Trust me, it's not worth pushing through because shoulder injuries can get quite persistent (as it did in my case by pushing through some training sessions)
