I suffered a " crush accident, left thumb. er x-ray turned up fractured and crushed nerve at the finger tip. the pain has subsided but something stic?

Question is unclear: I'm glad the pain has subsided. I don't understand the question that you wrote, 'something stic'. There can be unusual sensations at the site of a crushed bone and nerve. ( by the way, X-rays can't show nerve, just bone) If you indeed had a crush injury and all you have is tingling sensation without pain, that's a good result. These things can heal with time.
