Do you think cervical nucleoplasty using coblation technique is helpful in c-hnp? i received such procedure 4 weeks ago but no effect yet...

Ask questions: There are many "minimally invasive" spine procedures that sound great on paper and even have some +ve studies. B4 doing any procedure, ask how # your surgeon has done. If it's not covered by insurance ask why not- if a procedure costs less than usual surgery and has "wonderful" results, they will jump at covering it. Lastly, for hnp, these procedures should be done for arm pain, not neck pain.
