Lichen Sclerosus - what about using a pari bottle

Hi all LS sufferers. I've had surgery for labial adhesions--3 months ago. I'm still having sharp, strong pain when I pee. The surgeon's NP says to use coconut oil or olive oil. They also say I will have to use estrogen cream nightly for the rest of my life. I don't have a problem doing that but it does nothing for my LS. I began using clobetasol about 5 days ago and initially it seemed to help. Now, not so much. I've read that some have began using a bidet to help their LS. How many have found that helpful? I have a pari bottle with an extendable ?neck that is very easy to use but just checking if any others have tried this and what has been the results. Thanks all.
