Go and meet a hand surgeon immediately to ensure that no serious damage has been done to your fingers! Crush injuries like these are very commonly complicated with fractures
of the small bones of the fingers which, if untreated promptly, would give rise to complications and decrease in the range of motion of the fingers. Ultimately, the function of the hand would be grossly affected. Even if no serious damage has been done, it is best to splint
the hand in the "functional" or "glass-holding" position because it would decrease pain and at the same time lead to best functions in the long run.
