I have a MLS class IV cold laser (different company so can’t speak for this K laser machine) in my clinic and use it successfully for most patients in treating pain and inflammation. The only way to know is to try it, if there are no contraindications of course. I do not know your story so just a word of warning. If you have a skull base CSF leak the laser may induce brain drain and lead to worsening symptoms. It is never to be used over the thyroid gland. It will not take away the elongated styloid or calcified S-H ligament or fix any vascular stenosis, but it may help with pain related to inflammation.
Hope this is helpful, best of luck to you!
