I have begged my horrible gp to make another referral to a neurologist I have heard is most interested in b12 deficiency and peripheral neuropathy. Appointment has arrived. So... I have one shot. Do I launch into description of the terrible pains I have in my feet and burning legs - or my moan about getting injections every 2 months....or how poorly I am after about 2/3 weeks.... do I confess to si? Please please give me your advice.
