Wisdom teeth pains after extractions?!

Wisdom teeth pains after extractions?

I got my wisdom teeth pulled out about 4 days ago and on my right side i have major pain. Its not pain pain, its like a toothache sorta pain. Is this normal? i know my right side did impact another tooth so could that possibly be the reason?
Also, how would i know if an infection occured because i remember i always played with the right side because my stitches came loose and it was irritating. another thing, ive recently been getting alot of headaches, are headaches to wisdom teeth extractions?
Lastly, can someone explain the reason for elevation of head, when i do bend down or pick something up, the pain does pick up.

thanks for the help =)

Getting a tooth pulled is bad enough, wisdoms are almost unbearable. I had mine pulled 2 at a time. I had all the same aftereffects as you do, bu I wouldn't take any chances - tell the doctor, just in case.
