Thank you for consulting with us at Doctor spring. It is helpful that you have given us a detailed description of your symptoms. I understand that your first symptom was headache for a few days then you developed a upper respiratory tract infection and slight dizziness. Later, nausea, body ache and ear ache set in after which you have experienced some voice change and severe body ache. The other symptom that you mentioned is that you have loose stools with streaks of blood.

From an assessment of your symptoms it is most like that your flu got worse and spread to your throat and ears. That explains symptoms of voice change and ear ache. The ear, nose and the throat have a common origin during development of the embryo and so, they are often infected together during an upper respiratory tract infection. What starts as a rhinitis (infection of the nose) with a running nose or a blocked nose develops into a pharygitis (infection of the throat) due to spread along the pharynx. The throat infection then spreads to the ears through a structure called the auditory tube.

Most of these Upper Respiratory Tract infection.
