It's not uncommon for a primary outbreak of oral hsv1 to cause gum sores, but after that, recurrences will most likely be on the lips. A sore on the palette isn't likely to be a recurrence. Maybe you burned your mouth, or have a canker sore, or something along those lines. If it lingers for another day or two, see your dentist or doctor.
It’s just weird cause it’s been in the same spot n I know canker sores are more of soft pallete n I never got in there before hsv1 n it hurt when I ate a bit
