I went to the doctor for a chest infection and cough..also diarrhea. He lectured me that it was probably viral...but he would give me antibiotics if I want. I knew it could also be bacterial or fungal. He took no tests and barely listened to my lungs. I told him it was 8 days into this sickness...and that I also had a very strong metallic taste in my mouth and no appetite! He said he had no idea what that was!!!! It is now over 3 weeks that I have had this same thing and not getting much better except the diarrhea is gone. I looked up symptoms online and I believe I have bronchitis....but it still doesn't explain the metallic taste which definitely came at the exact moment I got sick! Any ideas what I might have and what test should I ask for?
