"It's going to hurt."

"It's going to hurt."
 

What are typical ways to say "it's going to hurt."
(Eg. you're at the doctor's office and they're going to stick a needle in you.)

you'll feel a pinch /vas a sentir un pequeño pellisco.
But is you really want to warn about something being painful (like something that may require opiates) you would say puede ser doloroso.

This is likely to be different from one region to another, so I can only talk about the doctors and nurses I know.


When the procedure is imminent:
- Un poquito de dolor. (Even when they know it will hurt a lot, but they don't want to scare you.)
- Un dolorcito. (This was my dentist.)
- Un piquetito. (When there is a needle involved.)
- Un ardorcito. (When the liquid of an injection is entering the body, for example.)

Very few of them say "va a doler", but it's not completely unusual.


When there are other feelings involved or complex procedures, they tend to make more personal sentences instead of impersonal phrases:

- Le va a doler, pero por favor no se mueva. http://forums.tomisimo.org/picture.p...&pictureid=920
- Se va a sentir un poco mareado(a). / Va a sentir un ligero mareo.
- Le va a dar mucho calor, pero va a pasar pronto.

Thanks, Angelica, but I'd like to make it more general (not doctor-specific).

In general: "It's going to hurt."

"(Te) Va a doler" or Poli's suggestion "puede ser doloroso". Anything depends on the context. :)
