I've been feeling faint for weeks. had lots of tests. all normal. but my ears especially my left is hurting and sore. no infection. but i feel off balance and sick. what could this be. have ringing aswell and my war feels blocked sometimes?

It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!

In a case like this, I recommend consulting neuro otolaryngologist at a department of otolaryngology at a university hospital near you. Bring all pertinent records and test results with you.
