The roof of my mouth was very painful and swollen this morning, as if I had scalded the entire mouth. My lips were also burning. It made it extremely difficult to eat this morning. Thankfully here at lunch time the pain is going down and swelling in the roof of my mouth is a little less. My lips no longer burn, but my tongue feels like I licked sandpaper. Does anyone else get this? Or know what it is? Although today is the worst I have had, honestly I have had this off and on since I was pregnant with my now 21 year old daughter. Which is when the chronic sickness started. Normally I get very mild itchy/pain in my mouth before the sore throat kicks in, so I expect tomorrow or soon I will feel sick. If this is a virus, obviously Valtrex isn't touching it, its making it worse?
