I am post op 3 years now.
Dilation is not always a pain, but it does take time and it needs to be a priority thing to do.
At 6 months post op, you should only need to dilate twice a day or maybe less. If you are having some issues, then keep it at 3 or even 4 times a day. No matter how long it takes to get full depth, just do it and keep your dilator there for about 15 minutes. Rotate the dilator and move it from side to side. If you need to, start with a smaller dilator, then go to a larger one right away.
Are you having any pain when dilating? If so, maybe a call or e-mail to Dr Ting's office is in order.
