<s>[INST] Lately, for short periods of time, usually 2 or minutes, my lips, gums, face and even my fingers on my right side only, get very tingly and kind of numb. I have had 7 back surgeries... but all in the lumbar area. I am getting a bit concerned. Thanks for your help, Todd [/INST] Dear Todd,Considering the fact that you had a past history of multiple lumbar surgeries, the symptoms as mentioned in your post can be attributed to:1. Compression of nerve fibers at the cervical region, either due to mechanical compression or spasm of paraspinal muscles.2. Inadequate hydration status & electrolyte imbalance of the body.3. Dietary deficiencies of certain nutrients like Iron, Calcium, Vitamin D, Vitamin B12, Folic acid, etc. which help in blood formation & nerve conduction.4. Peripheral neuropathy caused due to any fluctuation in blood pressure or blood sugar level.Symptomatic relief can be obtained by intake of nervigenic agents (like Vitamin B6, Vitamin B12, Folic acid) as well as multivitamin & multimineral supplements including iron, calcium & Vitamin D needs to be added in your diet.Physiotherapy & postural exercise will also be helpful.If symptoms still persist, kindly consult a Neurologist & get a complete Neurological examination done.Certain investigations like complete blood count, serum electrolyte estimation, fresh estimation of blood pressure & blood sugar levels & nerve conduction studies will be helpful to rule out any pathological cause for the symptoms.Wishing you a Good Health.Take care. </s>
