I don't have a single joint in my body in as good a shape as your shoulder. Sounds like you get to learn how to train through an injury. Figure it out.
Here it is
MRI Shoulder LT
There is a small trace of fluid around the long head of the biceps, but no significant injury is demonstrated. The rotator cuff tendons are intact with no evidence of a tearing. Minor signal change noted in the anterior supraspinatous on the PD images suggestive of a mild tendinopathy.
Normal glenohumeral joint
There is a small amount of oedema in the distal clavicle at the acromioclavicular with mild synovial thickening.
Opinion: The visualised biceps appears unremarkable. Minimal tendinopathy in the supraspinatous tendon. Minor bone marrow oedema in the distal clavicle.

I’ve tried pressing through it but the press starts to slack to one side as the pain gets worse with increased load. This is the most frustrating injury I’ve ever had.
Lower your reps to 3s, keep the weights up. Take tylenol and ibuprofen 1 hour before you train, after you try the 4-ibuprofen-4-times-a-day-for-5-days-with-food protocol. Should help.
Your long head of the bicep tendon can be pulling on your superior labrum at the location it is attached to. MRIs do not see this very well. The bicep can get damage from bone spurs or a mass on the undersurface of the acromion. Honestly shoulder surgery sucks but it isnt that bad. The small holes they make today u will have your arm over your head in a month if no rotator repair is done. That was my case. I hope yours is just inflammation. Anyway just keep volume low, it helps keep inflammation lower.
