i was in a car accident 8 weeks ago, since then i have not been able to hold anything in my left hand, if i try to move it i get pins and needles down my left side of my neck, arm and hand, The arm since has been making very loud clicking sounds and is very painful and the sensation of touch is different in left hand and arm to the right, ive been told i have wiplash, but having a x ray revealed nothing in my neck or shoulder. Can you please advise me what to do next
