Strep Infection with Sneezing and Watery Eyes

Patient: I was diagnosed with strep throat where I was also developing a neck and chest rash. I was given antibiotics which I have been on three days. However, I am not sneezing and my eyes are watering, and I am coughing relentlessly. Is this typical with strep or have I developed something else? How can I make it go away. I’ve already missed a week of work.
