Almost 2 weeks and still in pain

Full thickness SS tear and bicep tendon repair 13 days ago. I feel like I had less pain a few days ago, now it seems like it never goes away completely. Daytime is better but sleep is rough, have to be in a recliner and then I end up in a painful position that wakes me up. Surgery follow up in a couple days, I’m hoping to get some advice on more exercises and maybe some adjustments to the sling, because I feel like I can never get it adjusted so I can completely relax.
