For at least the past couple months I have being experiencing subtle, but noticeable, shoulder joint pain (roughly feels like it's located in my front delt) when doing any front/horizontal fly/pressing movements. It's strange because I don't even do that many chest movements a week (8-10 working sets spread over two different days), and get adequate recovery between these workouts (72-96 hours, decent sleep, with more than enough calories as well as protein).

What should I do? Deload for a week or two? Or is there anything specific I should implement into my recovery/workouts to prevent this issue from happening now or in the future?
