A couple of months ago I was diagnosed with herpes simplex having a blistered area of skin near the base of my spine. No treatment was given and the blistered area has cleared up. I do get cold sores.
Two weeks ago i went to the dentist and had a cleaning and x ray. The next day my tongue became swollen and white spots appeared and I was unable to eat for two days because of the soreness. I called the doctor after the swelling went down as I could not taste anything and my tongue was furry and felt like sandpaper and was prescribed a mouthwash but now after two weeks I still have no taste and the horrible feeling in my mouth continues. I am going to visit the dentist to see if there is a connection. Is a blood test a good idea?
