Sounds like you got yourself a doctor that learned the frontal way which should heal faster and less drainage since your using a 7 day dressing which is usually water proof for showers not baths but it will adhere better if you can wait.
Be careful with the chlorhexidine it is cytotoxic so if you have any scratches it could burn maybe put a dab on if doing it yourself at home want a few minutes to see if it bothers you. Keep it away from soft tissue areas just only on regular skin.
Yes those surgery’s are a blessing for so many. PT physical therapy will probably come get you up sap.
When turning in bed try log rolling and roll to unaffected side keeping affected side aligned. To get up drop your legs while using your arm to push up, sit there for a minute cuz you just had surgery plus drugs a few reasons don’t just try to jump up plus your BP will drop when you rise. So you don’t fall.
