DRY COUGH, PAINFUL THROAT!

A week or two ago I was complaining about my throat hurting. It sort of comes and goes. And right now, I have it, plus dry cough. My throat is painful especially when I cough. I am taking Benadryl at night. Few nights ago it seemed that the medicine was working. But last night I was bothered by the cough. I was coughing and coughing a lot eventhough I took the medicine. Oh… I hate cough. I hope it will go away very soon. And I hope my voice will not go away since I feel like it. I was wondering if I am allergic to something or I just got this from my kids at work. I tried drinking much water as much as I can since I’m not good drinker. Hoping this will help.
