Sir, I have leukaplakia, chest pain, upper gastric pain, pain under my right rib cage, pain at the lower mid region of my abdomen, pain at my pelvics, a persistent dark/pale yellow urine, sight of some growth in my throat region all my symptoms are characterized by pain. Am I having a metastatic cancerous tumor? or is it liver or gastric disorder that is causing my symptoms I am scared though I will be having a gastroscopy and an ultrasound this weekend...pls I need a clue on what may be causing all these syptoms
