Thanks for writing your query.
Neck pain can be due to Cervical spondylosis
. You should get physiotherapy
done for your neck pain.
Physiotherapy will help in relaxing the muscles and will give relief from pain.
Pain killers like Diclofenac
along with muscle relaxant
like Tizanidine 2mg, along with some antacid will also help. But these medicines should not be taken for prolonged periods
It will be helpful if you get a scan of you neck done along with X-Ray Neck AP and Lateral view.
Doing hot fomentation and applying local pain relieving gel is also helpful.
You should take medicines only under medical supervision.
I hope this is useful to you.
