Thanks for writing in.
Your symptoms are suggestive of cervical spondylosis
with nerve root
irritation. I would suggest you to get yourself clinically examined by your doctor. Xray of neck will help in diagnosis cervical spondylosis and MRI
of your neck will help in finding whether there is any nerve root irritation and the cause for it.
Till then avoid using pillows, lifting heavy weights. Soft cervical collar
might help you. Neck muscles strengthening exercises can be done under guidance of physiotherapist.
Get well soon,
