I cannot say that I have seen acupuncture as a treatment option for IC. Not that it isn’t an option, I personally cannot remember reading about it. At approximately eight months he should be seeing improvement (quite a bit actually), however, everyone heals in their own way. The healing after RP has a great deal to do with how involved the surgery was and the skill of the surgeon.
When you say he hasn’t mad much improvement, exactly what do you mean. No control? Little control? Is he continent at night?
There are so many questions. You should have an abundance of responses from this community but they will want more information. You have certainly reached out to a wonderful resource though.
