Postpartum binder too tight causing abdominal pain

Im on my 2nd week aft birth c sect and have been wearing binder ever since. However, on a recent trip to polyclinic, I think i strapped my binder too tight that I cldnt breathe in deeply but I was carrying my baby so I just held the pain. Now a day after, my right side ribs to diaphragm area hurts so bad I cant sleep upright or on my right and I cant inhale properly by expanding my ribcage. It has this short sharp pain that hurts so bad. Please advice.
