Many possibilities: Possible causes include cervical spine stenosis, neurological disorders such as multiple sclerosis, gullain-barre or als, or muscular disorders such as polymyositis or statin-induced myositis. You should discuss the possible causes, appropriate lab and other tests, and treatment options with your friend's doctors. Or get a second opinion from other doctors.

Work up: Because symptoms are on both sides of the body, consider multiple (at least 2) lesions in the brain, a single lesion in the spinal cord if it is a nerve problem. Alternatively, there may be a problem with peripheral nerve or muscle. Start with brain and cervical MRI to rule out problems that require immediate neurosurgical treatment. If negative, neurology evaluation should be next.
