Your problem is caused by inflammation of the shoulders, neck and waist. You can do some adaptive exercises around the patient's muscles. (Low intensity, multiple times)
Shoulder and neck: exercise of trapezius and rotator cuff muscles.
Waist: Exercise of sacrospinous muscles.
At the same time, let your lover often help you massage around the affected area.
But in the end, I remind you that before making any decision, you must get the advice or approval of the attending doctor.
