I took orofer xt as prescribed by the doctor for low hb for 3 to 4 months. After 3 months my tongue started feeling a bit stiff and rough. I applied gels, drank barley water but it continued. A feeling of less flexibility. I consulted the same general physician but he said the tongue looks fine. One more month went by and the stiffness reduced. But the tongue became rough in texture and sometimes a burning feeling, though mild particularly when I ate spicy, even Normal sambar or dal. Felt very thirsty sometimes. Still not feeling fully normal since 2 months. ENT and dentist also say no problem. No visible sores or patches. Is this burning mouth syndrome or dry mouth? Or hormonal fluctuations?
