Hi, I'm 28 years old female, not smoking, drinking glass or two of dry wine with dinner, gave birth 4 month ago. Started taking BC pills Cerazette two weeks ago. From the morning I have like a lump in my throat feeling and ache when taking a deep breath. Lump sensation comes and goes, especially comes when I take a seat. I'm worried that it can be something really bad like cancer... What do yo think?
