Delayed flare-ups? Does anyone else get pain 2-5 days AFTER the trigger?

Hey everyone,

​I have a small (yet painfull) intrasubstance supraspinatus tear and impingement, currently doing PT and trying to avoid surgery.

​I’ve noticed a very specific pattern with my flare-ups and wanted to know if anyone else experiences this. When I overdo it—whether it’s pushing too hard at the gym, carrying heavy grocery bags at a slight angle, or sleeping directly on the shoulder—the pain doesn't hit me immediately. Sometimes I don't even feel it the next day.

​Instead, my flare-ups operate on a massive delay. It usually takes anywhere from 2 to 5 days for the inflammation to really kick in and hit a 7/10 pain level.

​Because of this delay, it’s sometimes super hard to isolate exactly which movement caused the issue.

​Does anyone else experience this 48-120 hour delay for flare-ups? Is this normal for rotator cuff/impingement issues, or do your flare-ups happen immediately?

​Thanks
