My dr told me I could take Benadryl
You can use saline nasal drops it will clean ur nose and relieve some of the PND. However,if this doesnt help much u may need a prescription nasal spray thats safe for pregnant women.
Are you sure your throat is soar from post nasal drip? I get acid reflux at night so bad I have lost my voice entirely for six weeks. I thought I had a weird cold and kept hoping it would go away. Finally went to the dr. And he said acid reflux. I was blown away. He gave me a perscription and eventually my throat healed from the burn. Now that im pregnant im not taking the perscription and my voice is back to scratchy and a little soar...
