I'm two weeks out from these two surgeries (breast Aug & tummy tuck). I'm trying very hard to work on my posture & always wear the abdominal band (marina) and bra provided. However my mid to lower back hurts so badly after standing for 5 to 10 min that I must sit down. Are there recommendations for exercises, stretches, garments that would provide me with more support through this time? I am doing the breast exercises daily as required. Thanks!
