I suffer from chronic pain and nerve damage to my left leg following a severe trauma some 12 years ago. The condition has got steadily worse and the nerve damage has left my leg hyper sensitive. I am now getting continual pain and a 'pins and needles' sensation in my left shoulder and occasionally in my right leg. Could this be linked to the damaged nerves in my left leg?
Pins and needles with hypersensitivity (allodynia= pain to non-painful stimuli like touch or hyperalgesia= pain out of proportion to painful stimuli like sharp) all indicate the you are experiencing neuropathic pain (pain from the nerve). Neuropathic pain comes from a damaged, irritated, or dysfunctional nerve. As an analogy, seizures are caused by nerve damage or dysfunction that sends abnormal impulses through the nerve that cause movement. Sometimes abnormal impulses from faulty wiring causes pain instead of movement. That is why anti-seizure medications work to relieve nerve pain.
Your leg pain started in the peripheral nerve after the trauma. Over time, this can lead to central sensitization in the spinal cord and brain. Usually, this central sensitization causes nerve pain to intensify or spread. Spread in which direction? Sometimes upstream towards the body (like foot to thigh) or sometimes to the opposite side (like left to right). Spread to a remote location (leg to shoulder) is less likely, so an examination of your neck and shoulder by your doctor is recommended.
Referred pain is different than nerve pain. Referred pain is usually a diffuse dull ache without numbness or tingling.
If you want a great book to read about pain, I strongly recommend "Explain Pain" by David Butler (available at www.optp.com).

i was in a car accident 2005 after i had shoulder surgury then neck pain for a long time after now i have nerve damage in neck,shoulder, and wrist can this be from the accident?
I'm not sure if it can spread ...
There is something called refered pain ... even though you injury is in your leg you feel pain elsewhere. I have a shouder injury with nerve damage and have constant pain in my neck, back,arm and elbow as well as my shoulder.
