I have not got full recovery after i twisted ankle, still hurts sometimes. can i go skiing?

Depends: depends on how bad the sprain is and how hard you want to ski... http://www.ehow.com/how_5587918_ski-sprained-ankle.html

Probably should not: You probably should let it heal well. Skiing can be tough on the ankle and you do not really want to injure and injured ankle.

What matters most?: What matters most to you? Basic principles: if the original injury was a simple twist, with no fracture or truly major sprain, you're in no real danger. Heavy use may slow healing a bit. But a ski boot provides excellent support. Ankle is better protected than with activities like tennis or basketball. If you love skiing, and don't mind it being a bit sore, there's little risk. Hope this helps!

Post trauma/ankle: Continued pain after an ankle injury "sprain" tear with normal range of motion (painless/absence of numbness and tingling), limitations in walking, further evaluation may be merited. Proper ski boots, ankle wrap, or brace, often offers relief in the absence of previously mentioned signs and symptoms. Scar tissue & adhesions sometimes occur post trauma. To be safe, and enjoy skii consult your doc-
