My face is darker than the rest of my body. All other part of my body from neck to my leg are even tone, except for my face. I always have this pain in my stomach every morning. Sometimes i can choose to ignore it, and it goes away after some minutes. At first the doctor said he suspected high stomach acid, gave me some PPI drugs. I have taken drugs like Lazanprazole, Ulcer kit, Chlarithromycin, methrodinazole and so on. On several occassion.
