Well this is all good news if you ask me! I second your opinion on doctors and how useless they are. It's sad that I've become better at diagnosing myself and am able to just walk into a clinic and ask for the proper prescriptions. Very disappointing.
Sounds like you have your PD figured out, which is great news. It seems like every case is slightly different and to know what really triggers your is great (and makes it easier to prevent). I've had it 4 times now, with the latter times not being as serious, I believe this is because I know how to catch it right away! However, each time I have done a month of antibiotics, just to make sure it's gone for good. I don't really like topical treatments.
I find it interesting that you think it's the SLS and not the Fluoride. I've gone back and forth between the two so many times, and even to this day I'm not sure which bothers me more. I've used whitening treatments before with no problem but then I've used certain toothpastes or mouthwashes that have made me breakout. Seems like you're probably right about the SLS. I really wish there was more information on PD and why it responds so well to antifungals but needs an antibiotic for the final kick. It's all so bizarre to me.
Glad you got the meds to finally get rid of this frustrating dermatitis.
