Pain on outside of wrist when lifting weights. so pulling a weight towards my body using my wrist causes pain on the right side of right hand.?

Wrist strain: Sounds like a simple wrist strain, or overuse injury of the soft tissues of the wrist. It's best to rest it, wear a brace or support, ice when possible and take Ibuprofen or other anti-inflammatory. Avoid or limit activities that cause pain or this can become more chronic. Go see your doctor if it's not improving within a week or so.
