Palmoplantar pustulosis for 20 years

Palmoplantar pustulosis for 20 years/woman in her 60s

I am a 60-year-old woman. In my case, palmoplantar pustulosis developed with chest pain. I underwent examinations at a general hospital, but no abnormality was found.
Subsequently, multiple pustules developed on the palms of my hands and soles of my feet. Development and ruptures of pustules are repeatedly observed. Daily Loxonin (loxoprofen) is needed to heal costoclavicular pain. Now I am still undergoing with dental treatments., I had been only taking the same drugs (biotin, vitamin C, butyric acid bacterium) for 5 years at a hospital in Akita previously. It has been about 2 years since the first visit to a physician specialized in palmoplantar pustulosis. I have palmoplantar pustulosis for over 18 years.
