"i was prescribed tramadol by an emergency room doctor until i can get in to get my wisdom teeth removed. i&#039;m supposed to take one pill every six hours, but only take one pill whenever i have absolutely unbearable pain, that doesn&#039;t go away within one hour. the pain relief is quick, within 20 minutes, takes from a 10 on the pain scale to about 5. terrible nausea, shakes, lightheadedness, and sweats if i don&#039;t eat plenty before or right after taking this medication. constipation also caused, clears up two or three days after ceasing."
