Almost 10 weeks,still discomfort in rcl joint of thumb(i fell). it's not really painful unless i push on the joint,something hits it,or i stress it?

Possible sprain: It may be a sprain, but if it is not improving you should have it checked.

Sprain vs ?: Swelling and prolonged pain in an affected finger that you jammed from a fall sounds more like a sprained thumb, a stretch or tear of the appropriate ligament, rather that a dislocated or broken joint or bone. Make sure you see an orthopedic hand specialist, possibly get an X-Ray or ultrasound, or a scan, if necessary
