Gargle salt water. Maybe its an allergy. I am 28+4 and have Pregnancy Rhinitis its pregnancy related allergies because of extra hormones it won't go away til I have the baby. I have sore throat, coughing, sneezing, stuffy/runny nose, ear aches :/ I have had scratchy sore throat for almost 2 months.
Kind of for me it's just like a scratchy, ticklish feeling usually drinking lots of fluids help. It feels like having a hair or something in there but really is just more or less a dry throat. Hope it goes away soon good luck
