Which septoplasty stents are the most well tolerated by patients?

How many options exist for septoplasty stents & why aren't there better and more tolerable choices for patients? I wish I had done more research on this prior to my septoplasty. I just had the stents removed today -- my experience was horrific, and I did not tolerate them well. There were times I felt like I would have a panic attack from the extreme discomfort. I was miserable 24/7. My surgeon claims the stents are advanced state-of-the-art but as the patient, they were barbaric and painful.
