Hi. I just had a routine colonoscopy. I woke up with severe sore throat and earache. It was painful to talk. I also had lots of phlegm which I did not have before the procedure. A couple hours later, I had a chills and fever up to 102.5 degF. I had symptoms of a flu with severe fatigue and body ache. Dr. prescribed Azithromycin. As of now, I m still coughing up phlegm with blood (pale red) a few times a day, especially when it s coming from deep inside. My fever came down to almost normal after 3 days. Starting to feel better every day but not quite 100%. What are your thoughts on this.
