Hello, this morning I swollowed a half headache pill and in sweden they are called Alvedon forte. Its a 1 gram pill that is very small and I swollowed a half and I think that it went to wrong throat and I coughed a little bit and now like 10 hours later i have a littlebit problem breathing. My chest hurts everytime i breath so I wonder if I really did swollow the pill in wrong throat and what should I do?
