How Can hearing Loss Along With Ear Pain Be Treated?

three years ago i suffered sudden hearing loss. It has not improved and sometimes the ear will ache. Ringing never stops. In August of 2016 I was suffering from congestion and coughing also I would loose my voice. I did not go to the doctor because I was a smoker and did not want the lecture. I quit smoking after 48 years. (been hell but...) In October I woke in the night very ill. admitted to hospital with severe pneumonia so much so they asked about a DNR. I completed the round of antibiotics IV and then oral upon discharge. X-rays since have shown that the pneumonia has not cleared and I am on a fourth round of Antibiotics. This morning i woke with blood on pillow. Did pulmonary function test today (very poor although the tech could not give me any results. She did say...A for effort. I have seldom been ill so am not a hypo but i feel and fear I have lung cancer. I asked for a MRI but was told they probably won t do one yet??????
