Hi RTFTAT,
There are certainly many people here, most of us in fact, that know how you feel. It is a very difficult thing to talk to someone about, even your closest friends, and/or family. I think we feel like we don't want their image of us to be affected in any way, even though good friends and family would be extremely understanding in most cases. Like me, you sound like you are able to mostly 'cover it up', and therefore not have to explain it to everyone, as unfortunately most people have no idea of what p even is, and they are never afraid to ask. And for that reason, spare a thought for the many people who have extensive coverage, and are asked those questions, and given those looks every day. I really admire those who don't let the p interfere with their every day lives, as we know how hard it is to just not worry about it, or to accept it. As far as dating, or being intimate, I understand that these times can be extremely embarassing and frustrating. But just remember that anyone who does not understand, or doesn't want to be with you, just because of p, is not worth having as a friend.
I really hope this new treatment you are going to try works wonders for you. However, I think we all know that anyone guaranteeing that a treatment will work, or that you will be clear in 2 months, is quite ridiculous. No single treatment works for everyone, and that is a fact.
If you are seeing a dermatologist, is there any reason why you could not try a biologic, like enbrel or stelara. These both have fairly good strike rates, and enbrel has given me about 90% clearance.
Also, have you tried barneys formula (vitamin d and ibuprofen thread)? This has given many people, including myself, some relief. Changing diet and eliminating certain foods has also helped many. While some of these may or may not work for you, they are well worth trying, and personally I would want to have some sort of idea what the treatment was all about, before parting with $500. We have all spent thousands on treatments that simply don't work.
Anyway, let us know how you go, and what the treatment is all about if you decide to give it a go.
Good luck.
