See your general doc: Not knowing your age, and in what order these problems began, it is not easy to tie them together into a syndrome or single disease or problem. Neck pain can be due to muscle spasm, which is reported to give rise to eye pain and headaches. This would not explain your leg pains. Something pressing on your spinal cord, such as an infection, or abscess could account for the whole picture.

Not EDS: These are not eds iii symptoms. When the brain's circuitry goes on overload due to panic attacks, anxiety, stress, people feel neurologic symptoms such as headaches, dizziness, sweating, tingling in the arms or legs or around the mouth. Neck pain from muscle spasm causes more spasm, more pain, etc. Main causes are internal stress, external stress, hormonal imbalance, medications, or anxiety.

Mitochondrial?: In many instances, EDS hyperextensible type is caused by an underlying mitochondrial disorder. EDS with mito may manifest as progressive daily fatigue, headaches, muscle/joint pain and swelling, dysautonomia, autoimmune disease, gastrointestinal dysmotility.
