I have been diagnosed as suffering from whiplash following a car acccident 5 weeks ago. I still haven't got full feeling back in my arms and legs and they tingle all the time. The pain over my shoulders and top of the back is constant and i am still on strong painkillers. Obviously not at work at the moment. How long does whiplash take to clear up? i thought I would be better after a couple of weeks...but no.
