Hello Dear Thanks for writing to us, we are here to help Regarding your problem, smoking is not a good habit and you are too young to make it a hibit. Please quit smoking. The second part is cervical pain which definitely is not caused by smoking, you need to get a X-ray done at the first place and consult an orthopaedician for further treatment. Meanwhile you can start calcium and vit d to help a bit, avoid painkillers. You can instead use tropical painkiller gels. Hope that helps Thanks
