I was sick with a cold and it turned into a sinus infection. Now, I am starting to feel a little better as far as the congestion goes but I am having trouble breathing, making it difficult to sleep because it causes sleep apnea. When I take a very deep breath in, I feel a slight tickle in my chest and that causes me to cough. Once I cough it feels better for a minute but then it happens again. It also seems as though I am having heart palpitations, but I am not sure. I am currently on an antibiotic and I am hoping this will help.
