Insane burning on abdomen and pain around navel after CoolSculpting

Though only 10-15% of patients experience the discomfort you describe, it is real and it is uncomfortable. Tylenol is usually effective in combating the discomfort.  Of the few patients of ours who have described the "late onset pain" that you are experiencing, we have found that prescribed Neurontin is very effective in alleviating discomfort caused by the nerves rebounding from the CoolSculpting procedure.  
Our practitioner has performed close to 1000 treatments and has discovered that of those patients who experience this pain, it is from treatments with the very effective and great surface area large treatment applicator.  It is possible the small applicators could produce the discomfort, but in our experience we educate our patients on the possibility of late onset pain especially with the large applicator.  
Rest assured that those nerves are not damaged, they are just angry and they will return to normal. It is a very temporary experience.  Contact your CoolSculpting provider for options.  
For comfort, some patients prefer looser fitting clothes and some prefer more snug compression clothing (like exercise pants or Spanx).  See what helps you to feel most comfortable.  Either icing the area or warm therapy can be beneficial (protecting the skin with a towel as barrier) - again - one or the other with likely feel more preferable to you.  
A trained and experienced CoolSculpting practitioner would not place the applicator directly over the navel, but even treatments around the navel can make it feel hypersensitive because it is involved in the treatment area.  If you have any concern about the area or possible hernia, do contact your provider for evaluation and peace of mind.  
A few more weeks and you should start seeing some change, but remember, the elimination of fat cells naturally is a gradual process, so the most dramatic results are a few months down the road.  Good luck to you and thank you for asking this question.  I hope the information is helpful to you. 

Hi toniacol, thanks for your question.  What you are experiencing is called late onset pain.  The earlier generations of CoolSculpting applicators, which used a deeper suction, did frequently cause this type of post treatment reaction, particularly in the abdominal region  For most who experience this, the pain begins around the 7th day and lasts about 5-7 days, sometimes a little longer.  The degree of discomfort varies from patient to patient, but what you describe is normal, so no need to worry.  CoolSculpting will not cause a hernia.  We recommend icing, which you are already doing. You may also want to alternate with heat. Compression garments can also be helpful. I would also suggest Tylenol or any other pain reliever that is not anti-inflammatory.  The inflammation is necessary to achieve the best results. Hang in there. The pain will pass, and your results will be worth it.  This is what we have heard time after time from patients who have experienced what you are going through.  If you decide to treat again with CoolSculpting, I would suggest trying the new CoolAdvantage applicators.  These newer applicators treat in less time, with less suction for greater comfort during and after treatment.  The vast majority of patients who choose CoolAdvantage find they have no late onset pain.  Good luck with everything.  I hope you feel better soon.
