do i have dry socket?

I had all four of my wisdom teeth removed 5 days ago, on a Thursday. The day after, I though that the pain was started to slowly recede, but then on Friday night before I went to bed I felt a sudden and horribly painful aching in the left side of my mouth. The pain was okay with the pain killers, and now that I've run out I've noticed that the aching has gotten a lot better since then. But I still feel the effects and when I eat something cold it is once again unbearable. I also read that a sign of dry socket is a bad taste in you mouth. I don't really have that very much but I can taste a very faint and odd taste coming from where the teeth were pulled from time to time, but not often. My dentist said he would call this week sometime to see how everything was going but until then, does anybody think that I have dry socket? Or is this pain normal and I'm just panicking?
