Hi Kieran,
Yes, neural mobilisations are gentle movements of the nerves. Sometimes referred to as "slide and glide" etc. Should be pain free.
Nerves only require a very small compression before they lose their blood supply (pins and needles and altered sensation are your warning signs!). Go easy. Ipsilateral C/S LF and elbow extension then contralateral C/S LF and elbow flexion is a common exercise.
Obviously it is much more sophisticated that and careful assessment of which nerve trunks, nerves etc are involved.
Sounds like she has some pyschosocial issues as well. Fear Avoidance, no idea of pacing, etc etc.
By all means check the C/S out but don't forget the holistic assessment.
Good luck
