I got all four of my wisdom teeth pulled last Thursday and I've been feeling great except I have this aching on my bottom left side (for 3 days now). I don't think it's coming from the extraction sites, but bottom molars feel itchy and ache, and I involuntarily bite down hard to stop it from being itchy. Sometimes it doesn't hurt at all, but then when I go to sleep I wake up in the middle of the night and it aches so badly for an hour and goes away again! Is this normal?? Any help would be appreciated.
