You have an infection of the ear drum called myringitis. Bullous means blisters have formed. These can produce clear or slightly bloody ear drainage. This infection can be caused by both viruses and germs (bacteria). Symptoms of myringitis include severe earache, slight hearing loss, and clear or bloody drainage from the ear. It is different from most ear infections in that there is no fluid trapped behind the ear drum.
Treatment often includes antibiotic ear drops and pain medicine. Sometimes an oral antibiotic may be prescribed. Until the infection is resolved, you should keep water from entering your ear by plugging it with a cotton ball covered with petroleum jelly when you shower.
SEEK MEDICAL CARE IF:
You develop a cough or other symptoms of a respiratory infection.
Your symptoms are not improving after 2 days of treatment.
You develop a severe headache or stiff neck.
