Few months ago I went to a hospital for sickness. Their diagnosis said that I was suffering from schizophrenia and prescribed me medicine for the same. But after a few days I realized that the medicines had real bad side effects. I stopped taking them and asked the doctor for suggestion, but he never called me back. After that I moved to another doctor and this time I had proper diagnosis. However, the issue is that the previous hospital is now calling me for the full payment. How can I fight this medical issue? Should I write a letter to the hospital authority to drop the fees as they had misdiagnosed me earlier. Please help with suggestions.
