Sorry to hear about this. About 15-18 months after surgery and salvage RT I suffered bladderf incontinence.and needed to wear pads. Where I went wrong was I did not change them quickly enough, not realising the effect it would have on my foreskin. Was not long before foreskin got very tight, extremely difficult to pull back and even more difficult to return. In addition, like you, I suffered split skin and pain. It was hell.
However, I chose NOT to agree to circumcision despite being urged by both my GP and urologist, Was in mid-60s at the time and had read that the cut might be bit risky for older people. So opted to treat with Trimovate instead, an ointment you apply to the foreskin three times a day for up to a fortnight.
Almost immediately things got a lot easier, but was advised to stop applying to cream after a fortnight. This meant the problem soon returned by which time it was ok to resume the treatment. Again, things got better quickly until once again after a week or two things got difficult again and I needed to resume applying the medication.

This pattern went on for quite a while but over time, as the gap between treatment and recurrence grew wider, I was able to reduce the dosage from three times a day for a fortnight to twice a day for three days.
That was 15 years ago and I#m pleased to report I still have my foreskinn, which is no longer a problem most of the time. Nowadays, the moment there's even a hint of soreness (about once a month) all I need to do is apply this miracle ointment just once or maybe twice and everyrthing is immediately back to normal again.
It's a regime I'm very happy to live with and I'm so glad I resisted the urologist's advice!
