<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here... i have had a strange twinge like feeling on the back left handside of my head throughout the day, and a slight muscle spasm around my nose for the last week now, which keeps randomly coming and going. do you no what may be causing this [/INST] Hello dear,The symptoms as mentioned in your post can be attributed to:1. Paraspinal muscle spasm and entrapment of nerve fibers at the head and neck region.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.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.X ray & MRI can also be carried out to detect any nerve entrapment.Wishing you a Good Health.Take care. </s>
