Got bit by outsidecat,in finger,to the bone I think,4 days ago since than I cant feel My finger?

I am assuming you didn't see a Doctor about this, do that now.
It might be some nerve damage in the finger, but it could be much worse.
If there is a chance that the cat could be rabid then this might explain the numb finger.
If it was then you need to get the anti-rabies injections as soon as possible.
