As we all know, psoriasis cannot be completely cured. Can only be muted. In Azerbaijan, at the Naftalan resort in sanatoriums, you can receive effective treatment based on Naftalan medicinal oil.
Passing 14-16 naphthalan baths in 21 days, you will get the maximum effect. We have special sanatoriums (for example, the sanatorium Gashalty 5 *, the sanatorium Chinar 5 * and the Wellness center naftalan 3 *), which the main treatment profile is the treatment of psoriasis. After undergoing procedures in Naftalan, psoriasis will go away for at least 6 months.
I'm not a specialist, not a doctor, and I don't have psoriasis. But I have three or four acquaintances whose psoriasis has passed. What helped them:
Everyone had a move: to another house or to another country. For all - in a drier place (for one girl from the sea coast deeper to the mainland, for others - to another country with a dry climate). Concomitant therapies are notable improvements in sugar cessation.
Another friend noticed improvements if she avoided the sun.
So, since doctors do not treat this disease, and have suffered for many years, some are still cured, based on the experience of friends: provide a dry microclimate, no humidifiers, etc. on the contrary - salt lamps - yes.
If possible, move. To another house, at least. Or even a different climate (but not humid). Not to the dacha, where it is empty in winter and everything is damp, not on the seashore. Live, see. If it helps, organize a global plan and move completely.
Give up sugar and watch the result.
Good luck. Good luck.
