CoolSculpting questions and concerns for a newbie. Is it normal to feel hungry all the time? (Photo)

CoolSculpting does nothing to directly affect hunger.  However, if you are uncomfortable or perhaps not sleeping well because of the discomfort, you may be experiencing some stress, which can increase hunger.  
It is fairly typical to have itchiness after the procedure.  It's ok if you scratch the area, you won't cause stretch marks to develop.  Furthermore, you don't need to massage the area.  If it makes the area feel better to massage it, then go ahead, but massaging the area after a treatment won't change the final results.  
Hope this helps,

Your hunger could be a result of your body working on expelling the fat from the treated area. Be sure to drink plenty of water (more than the daily recommend amount) and eat a healthy well balanced diet. To curve your hunger, try eating 5 smaller meals a day. There are currently no studies that show ongoing massage will improve your results, but it certainly doesn't hurt to do it! Scratching the itchy areas will not cause stretch marks. Try applying BioOil (found out places like CVS, Walgreens) to the area/s for relief. Many patients like the feeling of wearing a compression garment after treatment. Nothing proven yet to show a waist trimmer will help your overall result.
