I roke my pinkie toelast night- is it safe to stand on it and work?

Yesterday night I stubbed my right pinkie toe on a metal chair partwhile walking past it. It hurt but initialy didn´t seem that bad, so them I tried to move it and it still worked, but it crunched and grinded whan I moved it. It is twice as big as my left pinkie toe I have really small scrunched pinkies with almost no nail. Butit looks like it is at the right angle when I put weight on my foot. First it turned grey and purple, now after working all day at the factory(standing and walking with not many breaks) turned black and blue, and deep blood red in a collar around it even extending on top of my foot. It really hurt earlier, but I took some motrin and wore wide shoes and taped it to the other toe. Now he pain isn´t so bad 24 hours later, but I am scared to remove the tape cause it feels really vulnerable to being ´used´ and hurt again. I also want a doctor to see it. I think I should have iced it and suspended it last night but I didn´t want to believe it was broken, until it changed color and became unusable. It won´t fall off, will it? Or am I being a whiner?
Plus I am having congestion and getting over a cold, without antibiotics(taking echinacea, and waiting to see if the immune system can kick it; so far so good with gradual improvements every day), I went to work because I can´t afford to take off any more. the only bone other than this I have broken is my nose(I know, cartilage), and I had to have a septoplasty because it whistled afterwards.
