On my pinky toe its soft but swollen it feel like there is fluid in the area that's swollen what should I do?

Might need 2 B seen. Fluid doesn't accumulate without a cause. Typically, it's a reaction to an injury or irritation of some sort. You must consider trauma, infection, insect bite or frictional causes, to name a few. There may be some similarities in the symptoms for each, but other symptom can't be discounted. If you are unsure as to the cause, it would be wise to have it evaluated. Give it a day or two to resolve.
