About the same sorts of things that happen if you get stabbed in general, with the added bonuses of the possible transmission of blood-borne diseases (from the person who used it before) and the potential impact of additional insulin in your system. On the plus side, a syringe needle is somewhat smaller than a machete, so the likelihood of bleeding out is lower.
It is definitely possible. Get checked out with a doctor.

When you depress a syringe, the plunger moves downward, creating increased pressure within the barrel. This pressure forces the fluid inside the syringe out through the opening, allowing it to be injected into a target area or system. The action of depressing the plunger also draws in any air or fluid from the back, depending on the syringe's position and usage. This process is commonly used in medical applications for injections or drawing blood.

A gas syringe is basically a device that fills up with a gas that is produced and gives a volume for that gas. Gas from a reaction is forced into the syringe due to pressure and the syringe plunger is forced out (just like how you suck up a liquid with a normal syringe). It can be used to detect the volume of gas produced in a chemical reaction for instance.See the Web Links to the left for more information.
