Hey there my name is Whitney and I've had a cold on and off since the beginning of December. I have taken z pac and another 10 day antibiotic, i cant remember the name of it but it fights pneumonia and makes your mouth taste like metal. For the last couple of days my eyes have been killing me. They are tender to the touch and feel as if someone has punched them. It kills to move my eye balls from side to side and last night during my sleep I had the worst cotton mouth that kept waking me up. do you know what this could mean? I still have never gotten rid of my stuffy nose and cough. any advice on what i should get for my eyes and cotton mouth?
