Hi π
I have LS too. My initial symptoms were mainly itching and soreness. I now sometimes get bladder involvement in a flareup - symptoms much like a bladder infection basically. It's extremely frustrating when it happens.
To give you a little hope: I've had the diagnosis for several years, and I do think it gets better. My symptoms are manageable most of the time. I can usually stop a flareup in its tracks by starting treatment at soon as I feel inklings of it coming on. I have a healthy, very active sex life - much more so than when I was younger to be honest π My partner is aware my skin can at times be sensitive, and we have strategies for managing when that's the case. Most of the time, we don't have to worry about it though. I never did get to the point of actual narrowing or needing dilation, but I've heard many women who have had that, and come out the other side to a happier state.
Before I left Reddit, the LS subreddit was relatively active and supportive. You may want to check that out for more advice. I don't think there is a Lemmy community for LS, and probably there are not enough of us to start one π
In terms of treatment, the steroid ointment is the only thing that reliably helps me, and it's the only real proven treatment. I assume that's what you are using, right? If so, keep it up, it can take a while to get a handle on it if you've had untreated LS for a longer period. Once it gets under control, you may be able to only use the steroids for flareups, thats what I do now.
There is a another treatment that works for some people - Tacrolimus - but I've never tried it myself. I believe it's an immunosuppressant cream or pill, you could try asking about it if nothing else is working.
If the treatment does not help at all, I would go back to the doctor to confirm your LS diagnosis - it can often be a bit iffy to actually diagnose, and gets mixed up with other things. If steroids don't work, it may be something else. Did you have a biopsy done to confirm? If not, probably good to get one, even if it's not exactly fun.
In terms of tips, honestly the main thing I've learned is that my main trigger is stress. I can't always avoid that, since life happens. But I've put in place stress management techniques, and try to allow myself rest and recuperation when I need it. That's the only thing that has helped reduce flareups.
Hope this helps a bit. Feel free to ping me back if you have questions.
