Hello,
What I understand with the symptoms is they are neuropathic in nature. Here are the two possibilities which I feel on a provisional basis. One it could be 
carpal tunnel syndrome or it could be 
nerve entrapment anywhere in its course.
Having checked by an orthopedist should provide some insights to the history in a more precise manner as it needs a physical examination. Since human hand has 3 different nerve supplying the hand muscles for different functions we need to assess that first. 
Also, the nerve has the role of motor and sensory functions. out of which the 
numbness tingling pain is one the function under a 
sensory system of the nerve. Any disturbances to the nerve may alter the functions and aggravate the symptoms.
For now, I would say start basic static neck exercises which you can find online and also dipping the hand in hot water up to the mid-forearm so the wrist is completely inside the water and perform wrist flexion and extension. 
Why this two exercise is because if the nerve is getting trapped in the neck region the neck exercises should help release the pressure and why hot water is to reduce the tightness over the flexor retinaculum so the nerve trapping can get released. 
Hope I have answered your query. Let me know if I can assist you further.
