I have been taking ultracet (tramdol and acetaminophen) for 4 years (2-3 tablets when i have pain). is this okay? will my liver get damaged?

Possibly: 2-3 tablets per dose every 4-6 hours or only 2-3 tablets per day? Are you taking any other Tylenol/Acetominophen-containing meds? Liver damage & acute liver failure can occur at lower doses but is usually associated with using more than 4000 mg or acetominophen per day. If you're using only 2-3 pills per day, damage isn't likely.2-3 pills 4-6 times per day - you can easily damage liver.
