Does anyone know what it can be if your tongues orange but you haven't ate anything orange? I haven't been well for a few months and my bowel movements have been different. I keep getting a pain in my left side and back. Last night I had a bad belly right across the front at the bottom. I woke up at 3 this morning with bad pains and had to rush to the toilet and I know it's too much info but it was just like sludge. My hips and bottom of my back are really stiff and sore. I am worried and I see a gastroenterologist in 2 weeks because my liver function test was high.
