I was prescribed Biaxin XL for pneumonia and wish I never took it. I am going out of my mind. I am an artist and I couldn't paint nor choose colour. I was having a hard time walking, felt disoriented, panic, yelling out while sleeping. I am also suffering from intense pain in my neck radiating down my arm and up into my ear. I had a terrible reaction to sulpha one time and I should have learned my lesson then. I will immediately turn to natural rememdies from here on in.
