Hi Carmarie,
Sorry your here although you may pick up some very useful assistance.
You did the right thing sourcing out a Dermatologist yourself, LS is a skin disease and many doctors and gynaecologists are not useful as a large majority know little about it, they are not doctors or specialists that have expertise in skin diseases.
I have the same symptoms and were picked up in early menopause phrase. What you can expect is to be examined, Dermatologists are usually aware of what to look for with LS, is usually visible in white dots or larger patches. It usually appears in the genetalia or anal areas. Dermatologist will probably examine both areas. If there is conflict in opinions from one specialist to another, you can gain 100% confirmation by having a biopsy, I have had one front and rear, abit frightening but no need to worry that much about it as they only take such a small scraping of skin you can't even see where they've taken it and they give you some local anaesthetic to numb any pain, its quite quick, with perhaps a small bit of blood like from a scratch afterwards, relief is experienced after its done.
I was prescribed Vagifem for recurring soreness, I have had great success with it. Vagifem has been known to be very safe, I've not had any issues whatsoever with it and use it twice a week usually a Tuesday and Friday night before bed, put a very thin smear of olive oil on the applicator if your extremely dry and have trouble inserting it, helps, don't usually any lubricants like KY or anything else that may have irritants, the less irritants you have the better, or just insert it without.
I recommend that you find out as much as possible on the medications you've been given, there is much resource on them online. Be very cautious with steroid creams and ointments should be very very thin when applying, clob will thin the skin so you need to be extremely careful with any cream or ointment they give you but if you don't have a clear diagnosis I would be inclined to wait until you perhaps get a biopsy.
You may for a little while have a stinging or irritating sensation from Clob, I am on Diprosone OV Ointment and when I first started using that, I had abit of irritation but know that it passes after a few days, things settle down. Atleast give it a week before you go back to your doctor to report any irritations.
Questions you need to ask would be -
1. Is LS visible front and back?
2. If visible, please could you show me with a mirror so that I know where to apply the cream/ointment.
3. How much is a biopsy?
4. Do you have many patients that you are treating for LS? If not can you refer me to a LS Specialist?
5. What has been the most successful treatments LS sufferers have reported?
6. How many times a week do I need to use treatment, how often should I come back to see you?
7. Has there been any new developments with LS treatments?
8. What can I expect from the treatment? What should I look out for?
9. Is there a specific list of foods I should stay away from with LS?
You might like to find out if there is a female LS Specialist rather than a male and for the interim you might like to have regular weekly visits until your comfortable doing what you need to do.
LS is an auto-immune disease which may or may not open the opportunity up for other susceptability of other auto-immune conditions/diseases etc.
I get regular blood tests done and vaginal swabs so that specialist can keep an eye on things and check that there is nothing else going on.
Vula and Vulvadynia Clinics are a great place also to see someone, specialists in these areas for women. You may find them online as GPs, Gynos don't advertise them nor tell you about them, nor do Dermatologists as they all want your business and your money.
LS is a long term condition which needs correct and ongoing management. Failure to manage this condition/disease on an ongoing basis as directed, may result in cancer cells/growths growing eg. squamous cell carcinomas.
If and when you get confirmed, check out the 'Lichen Scerosis Yahoo' group online, the largest group worldwide (supposedly).
Hope info is of help and good luck.
