I started coughing really badly for a few days now. Before that I have some symptoms and I'm just now reading about whooping cough. I'm just wondering if there's a good chance that I have whooping cough b/c unlike ordinary coughs, I've started having a little bit of pain in my left shoulder/neck. I've read a few articles but it doesn't say anything about shoulder pains only chest/breastbone pains are symptoms. Any ideas? thanks!
