If you have pain/numbness/weakness going down neck, shoulders/arms and hands bilaterally, it could be cervical spinal cord and/or nerve root compression/flattening by herniated disc(s), bone spurs/osteophytes, hypertrophy, or ligament thickening. You should see an orthopedic spine specialist for evaluation and MRI of soft tissues in neck to see if you have cervical myelopathy/pinched nerve roots/nerves. You would want to have a neurologist do an EMG/nerve conduction study to see which nerve(s) are compressed causing radiculopathy to arms/hands/fingers.
