Hi.. The reason for your shock and numbness in your right hand fingers is your nerve...some nerve root would have got compressed ..in your neck that could lead to such symptoms... A disc bulge or prolapse can also lead to such symptoms... While reasons for a entrapped nerve root or disc bulge could be many more branding from Prolonged bad posture to degenerative issue of the bonesof the spine...in your case the accident would have initiated the issue worsened by the posture and work you do... If I were you then I would have met orthopedic doctor without any further delay to get my problem clinically evaluated and investigations to be taken to confirm the diagnosis and proceed with management.. Meanwhile I suggest you to have a good neck support..support while sleeping.. avoid lifting weights Maintain good neck posture while working...take frequent breaks...raise the monitor slightly up till eye level to avoid prolonged bending posture. Keep neck gently stretched to reduce spasm around the neck... Hope this is helpful for you... Kindly revert back in case you need any further clarification...
