You have long-term gastrointestinal indigestion, accumulated heat in your stomach (white spots on your teeth and nails, talking in your sleep), spleen deficiency, damp-heat fire in your liver, and insufficient kidney qi and water. If my analysis is correct, please consult a Chinese medicine doctor for reference! Eating Chinese medicine has a good conditioning effect.

Please don't worry too much. If you want to get better as soon as possible, you must first adjust your mentality. It's not cancer, it's blister sores (or root inflammation). But your ulcer is often a virtual fire. Pay attention to rest, do more exercise and strengthen your physique. I wish you a speedy recovery!
