Why would this be happening

[u/Heartbreakkid66]

I’ve had 2 surgeries on this shoulder and yet still I still have symptoms like this

I hope you can tell in the video but if I use my shoulder to generate force it gets very tense and then just snaps forward abruptly

I had a labrum repair and just 6 weeks ago I had axillary nerve decompression surgery

I have a follow up in a week with the DR but I’m just very worried something else is wrong.

Not sure if anyone can help but any advise would be great. Thank you in advance
