Hi, may I answer your health queries right now ? Please type your query here...Hi my dad has been sick for over a month with shingles inside his ear. He has had several complications since being diagnosed, sever coughing, coughing up clear fluid, major headaches, loss of appetite, sever vomiting and chest pain. We had to take him to the ER last night where they admitted him. After running several test today they have now found a cyst on his brain. What does this mean and could this be the cause of all of his illness.They have ran severa test on his heart and it has checked out fine.
