I've had severe allergies for 24 weeks! My whole pregnancy. I have been coughing and sneezing for this long! Now for a month now I have had ear aches, and sore throat. I take claritin once daily, delsum cough medicine, benadryl at night, for the pressure in my ear I plug my nose and mouth and blow air until I hear and feel a mild POP or use steam for nasal problems, I use saline non medicated nasal spray and gargle salt water, I'm gonna buy a humidifier to help too.
