Hi,
Since you have mentioned that you have 
neck pain as well as 
numbness in your  hand, it has to be related with 
nerve compresssion. This occurs mostly due to our lifestyle habits like usage of computers, watching lot of TV, bending while reading.
1) If your problem is severe you need to get 
X ray investigations done initially, followed by MRI only if required.
2) Do not take analgesics excessively.
3) You need to keep an erect straight posture of your back and neck.
4) Do stretching exercises, when you wake up lie on your chest then using two hand lift yourself up, in a arc like position and then lie down slowly. Repeat his at least ten times daily. This will surely relieve 
back pain. You can watch online videos for such exercises.
5) If your problem aggravates you need to get yourself physically examined and investigated through radiological methods like x-ray and MRI. 
Hope these suggestion help you. Contact for further follow up.
With best regards,
Dr. Suhas Chauhan
