Cevical radiculitis: Most likely the cause of your headaches is related to loss of the normal curvature of the cervical spine, affecting your neck muscles which are attached to the skull, causing headaches, which we call Tension headaches. This is due to bad posture while sleeping & sitting. Management will require obtaining cervical spine X-Rays, physical therapy, neck exercises.

Try real doctor: First, your numbness in hands after elevation raises suspicion of brachial plexus compression. This thoracic outlet syndrome symptom may be a trigger for the severe headaches, and appropriate treatment could reverse. May be rather complex issue if local physicians are not familiar with this. See if a neurologist can help. If not successful, a Concierge visit here online might provide help.
