Thanks for writing our query.
It will be helpful if you write the names of the muscle relaxants you have already taken.
I would suggest that you should get an X-Ray of your neck to rule out the possibility of cervical spondylosis
Also add a pain killer like Ibuprofen
one tablet twice a day after meals along with an antacid
20 mg along with the muscle relaxant.
I hope this is helpful to you.
