I have been suffering from what I believe are allergies.  Symptoms primarily consist of constant draining of sinuses down the back of my throat.  This has been going on for over a year now but since July the symptoms seem worse with a constant sore throat and my tongue is tingling with slight metallic taste in mouth.  Ive been taking otc Zyrtec   daily.  Is this something I should see my doctor about?
