[/INST] Hi,Welcome to HCM.Bleeding gums can be due to bad oral hygiene, and due to inflammation of gums called as gingivitis.Coughing up blood in saliva is definitely worrisome. Itching could be due to many reasons but most common is allergies to food.I suggest you get a detailed examination done by a GP near you to rule out causes of these symptoms.I would also suggest you get a complete lab workup to rule out bleeding disorders, and any kind of malignancy.Thanks. </s>
