Following abdominoplasty, it is usual to have a stretching feeling (tummy tuck). It might take 3 to 4 months for the discomfort to go away. The stretching sensation is fairly frequent and is caused by a mix of muscle healing and skin tension. These feelings should decrease as your body heals. Stretching can be avoided by lying in an extreme lateral position for several days following surgery. This will allow the muscles to relax and avoid tightening up again. If you experience severe stretching pains that don't go away, see your doctor immediately. You could be developing scar tissue which will cause permanent damage to muscle and tissue. Abdominoplasty involves the removal of excess skin and fat from the abdomen. As your body repairs itself, the muscles and tissues underneath may feel tight or stretched out. This is normal and should go away over time. If you are experiencing pain when moving your stomach area, see your doctor so that any underlying problems can be treated promptly.
