Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. No, shingles never causes anaesthesia or numbness. It can causes paresthesia, means altered sensation like burning, tingling etc. All this symptoms always be associated with the pain, which is hall mark of shingles. I advice you to please get your complete examination done as it is very initial symptoms of big things. Numbness has wide etiology for its occurrence. So once the cause is known treatment should be guided on that direction. I advice you to wear a soft footwear other wise the numb area get ulcers. Once formed the ulcer will be very difficult to heal in such a area. Please maintain the good hygieneic atmosphere around the toes as it can prevent the future infection. Please take vitamin B complex tablets under doctors guidance until you visit the concerned specialist. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
