You most likely have tinnitus if you occasionally hear buzzing, ringing, or hissing sounds coming from inside your ears. This symptom could be a sign of a number of ear diseases.
FIRST AID FOR INSECTS IN THE EAR
You can try to carefully remove an insect that has been trapped in your ear by tilting your head so that the affected side is uppermost, followed by pouring warm water into the ear (it is easiest if someone assists with this). The insect should then escape. Consult your doctor if this is unable to remove the inset.
