It is highly unusual to have any (especially excruciating) pain during the procedure. For the first couple of minutes, patients need to adjust to suction of the applicator. Patients do not find this painful but uncomfortable. One patient recently described the sensation as a "toothless shark" - relentless but not painful.
Post procedure most patients have mild tenderness but no pain. Even in the rare case like with myself that there was pain after the treatment, it is not during or immediately after the treatment.
Review your medical history with the treating physician. There are a few medical conditions that would not make you a candidate for the procedure. You may have one of these and not previously realized.
It is unusual to have excruciating pain during the CoolSculpting procedure. Most patients report mild discomfort for the first 5 minutes which usually subsides as the procedure progresses. There is also some mild discomfort after the post-procedure massage which is reported as "tolerable" by most patients. Make sure you follow up with your doctor to have your concerns addressed.
The reaction and pain that you are describing is not typical of coolsculpting. The initial few minutes there will be some soreness until the area is frozen. The pain that you are describing should be discussed with the treating physician and the company as well. For the best results please consult a board certified dermatologist with a great deal of experience with CoolSculpting and other cosmetic procedures.
In almost all cases, the transient discomfort of the suction subsides when the cooling phase starts. If you have continued discomfort, talk to your provider. It sounds like perhaps a different applicator should have been used rather than the CoolMax if it did not fit your contours adequately, thereby causing pressure points and discomfort. All of this should subside however.
Your description is not typical for patients we see. Many say they feel the immediate discomfort of the suction drawing the roll of fat and skin into the treatment head, and between the cooling plates. Then they report some cold sensation for a few minutes, until the numbness begins. This tends to last the remainder of the session. We do occasionally have different patient reports, but are able to address any concerns.
Please stay in contact with your plastic surgeon about your experience.
The area being treated should have discomfort until the cooling starts. This is in the beginning of the procedure and lasts the first 4 to 8 minutes roughly. The next time discomfort is experienced is upon removal of the device and the massage period that lasts usually 3 minutes. At that point the discomfort being experienced should be able to be managed with tylenol.
There can be some discomfort with the procedure. It can vary from patient to patient. The experience you describe can be normal. Please see your doctor if the pain persists.
