What's porphyria?

Disease family: Maybe 1 person in 1000 is born with a strong tendency to porphyria cutanea tarda and some forms of hepatitis can bring it out even in a normal person; it blisters and scars sun-exposed skin. Other porphyrias masquerade as abdominal pain, mental illness, constipation, low sodium, and chronic nerve pain -- and screening tests are often done wrong. Good luck.

See a hematologist: This is a genentic disease of the blood. You would best be served by seeing a hematologist.
