Hi! I had Coolsculpting (i believe it was called Zeltiq back then) on my abdomen in 2011. I remember it working a little bit but it causing shooting nerve pain across my stomach for about a month. Has the technology improved? If I had nerve pain back then would I likely experience it again if I did another treatment? My BMI is 21 and I exercise regularly but have about 2 inches of fat on my belly. Other than lipo, what is the best non-invasive option? Thank you in advance
