Ear pain and bleeding may be caused by trauma, papilloma of the external ear canal, squamous cell carcinoma of the external ear canal and so on. 1. Trauma: If the ear is subjected to violence or impact, it will easily lead to skin damage of the external auditory canal or tympanic membrane, which will cause severe pain in the ear and lead to bleeding secretion from the ear canal. In addition, if you pull out your ears too hard, it may lead to damage to the mucous membrane skin of the ear canal, resulting in symptoms of ear pain and bleeding. 2. Papilloma of the external auditory canal: If the patient suffers from papilloma of the external auditory canal, it may be caused by the presence of a foreign body in the ear canal for a long period of time or chronic irritation, which will cause the mucous membrane in the ear to break down, resulting in earache and bleeding, accompanied by congestion, swelling and other discomforts. 3. Squamous cell carcinoma of external auditory canal: if malignant tumor occurs in the external auditory canal of the patient, rapid growth of the tumor may occur, and when the tumor ruptures, symptoms of bleeding from the ear may appear, accompanied by earache, tinnitus, stuffy and swollen feeling in the ear and other discomforts. Patients with earache and bleeding should go to the hospital in time and get a clear diagnosis after systematic examination.
