###Human: After using larger size silicone ring to loose the foreskin, I experience pain. Why? ###Assistant: Hello. I have gone through your queries. The only solution to phimosis is circumcision. However, you may have minor vascular injury inside the foreskin due to the use of a tight silicon ring. You can wait and watch to buy some time for natural regression of the swelling or else you can straightway go for circumcision after consulting your local urologist. By few days to weeks, the swelling will reduce. But the permanent solution of phimosis is circumcision.
