It seems that she has cervical spondylosis
and it is giving acute attck of dizziness
and sweating ( may develop vomiting
too) also due to it. Vertin
can be given and she should avoid making any sudden neck movement - especially bending and turning. She should turn competely if she needs to look back. She will be gine a collar to wear ,may be the hard one. This will.give her neck a desired rest for some.time. she should.continue it for few weeks.
I hope she gets better fast.
