No its not that bad. When you first get them on it may hurt for a little while. If it gets to bad, take some medicine. After like a day or two it wont hurt no more! And then just take care of them and your good! You will get used to them and not even know.
for the first few days & speaking will be a little difficult for the first few hours, then tightening will make you sore for about a day or so every time after that, but it's all worth it, I speak from experience :)
