Im 37 weeks pregnant. I am swelling all over hands, face and feet. I have had a nasty cough for 5 weeks now and sometimes I can't catch my breath back for a few seconds or so. My joints Hurt all over. Also feel like my throat is closing up. I have been to the ER and they only checked my blood pressure and O2 level. They think it's just allergies and gave me singalar and some cough pills. And nothing I can do works. I am miserable

Go back to the Doctor or go to the ER. This is nothing to play around with.
