Air bubbles under skin after lipo - is this normal? Should I be concerned?

It is not uncommon to have "Crepitus" - the popping and crunching sensation after lipo. It is caused by air within your subcutaneous tissues. crepitus is usually harmless and will resolve on its own with time. However...In some cases, crepitus occurs with a severe infection or punctured lung or abdominal visera. This crepitus is usually associated with several pain, fever, chills, shortness of breath, racing heart, and a continuously worsening condition. Since you were able to type this question and had no other complaints...I doubt your crepitus is of any concern. I would recommend talking to your plastic surgeon who can ask you some key questions and if they have any concern, see you in the office. Hope this helps.Paul

Subcutaneous emphysema is not uncommon after the procedures you have had.  Wearing your compression garments will help it resolve more quickly.  It is not dangerous in and of itself.
