I'm a sensitive little thing!

Yesterday and today I've noticed the roof of my mouth has gotten more sensitive, and it feels quite strange.  Yesterday I started to notice that when I would drink it would sometimes feel like liquid would go up my nose, yet it doesn't.  I've occasionally gotten the same sensation today but I've also found at time that the roof of my mouth is getting sore so when I touch it, it sometimes hurts.  I guess the numbness is wearing off, I guess that's both good and bad.
