I am suffering from slight numbness on cheeks [below eyes] (few times one side, few times both side) upper part. If I rub with my hands slightly just once on the numbness area, it will go. After some time it reoccurs. I am suffering from b12 and d3 deficiency, also varicose veins and sinusitis. I daily ride 2 wheeler for around 3 hours in afternoon and 2 hours in evening from 7 pm.(totally around 5 hours) And also I go for walking at around 7 am. If I close my nostrils and observe the numbness, it disappears for almost upto 5 minutes and reoccurs. I think it may be due to riding and walking in cold or due to deficiencies. So, can you please provide the possibilities of reason. And also can you please advice the medication for the above. Thank you.
