Sometimes when i wake up in the morning i find blood in my cough and feel pain in inner ear..but this happens once a while and then recurs after days?

ENT: You obviously have an infection or inflammation in your respiratory tract and or inner ear. Consult a physician ASAP.

Bloody sputum: Are you a smoker? You need to have a chest Xray done with these symptoms to make sure there is nothing serious going on. Have you had any other symptoms? fever, chills, fatigue, weight loss? Have you had a PPD test to check for TB? These are some things you need to discuss with your doctor. Feel better soon
