Thanks guys for taking the time to comment,
akpolarmom - I've taken your advice and placed "unrelenting" at the start of the sentence to make the continuous nature of the rain stronger - thanks
US -if you're interested, the surrounding prose is in "review my work" well, two paragraphs are anyway.
There have been other comments on the personification or "pathetic fallacy"

so, anyway I have changed the sentence and it now reads:
"Unrelenting, ice-cold rain spat in her face like hundreds of tiny needles prickling her sallow skin" this is still work in progress so it may change again yet

Thanks again, appreciate your help
