PT does not help some patients in certain cases, so if you find it necessary, see if you can request a PT who may have specific training in your PN and other disorders. My neurologist sent me to a certified Brain/Spine PT to address my migraine/hemiplegia crania/proprioception and eye/gaze discrepancy issues at the medical center affiliated with the medical school. Best for me by far.
While talk therapy can help, depression meds need to be addressed by the MDs. I have previously used Paxil (stomach issues) Prozac and Zoloft for short-term depression (less than a year) Gabapentin was originally an epilepsy med (so acts on certain areas of the brain) now widely used off label. I cannot use even at a low dose at bedtime: loss of coordination, brain fog and sleepiness/exhausted feeling the next morning for hours. Amitriptyline was tried for my headache disorders. Not helpful for me. Sometimes we are not a candidate for a class of drugs....#biology.
Interference with "Activities of Daily Living" should be sufficient criteria to reevaluate in my opinion
