My French Friend’s Brother Has Recently Complained Of Finger Neuropathy

My French friend’s brother has recently complained of finger neuropathy and pressure behind one eye. My friend is an English teacher so I will refer her to your website as she will be more knowledgeable as opposed to my third hand hearsay. She feels her brother is in denial.
Thank you so much for your kindness.
