Dear Bamy, The symptoms can be attributed to inadequate hydration status & electrolyte imbalance of the body or dietary deficiencies of certain nutrients like Iron, Calcium, Vitamin D, Vitamin B 12, Folic acid, etc. which help in blood formation & nerve conduction. Symptomatic relief can be obtained by intake of nervigenic agents as well as multivitamin & multimineral supplements including iron, calcium & Vit D needs to be added in your diet. If you still find any difficulty, kindly get certain investigations like estimation of blood pressure & blood sugar levels, Thyroid profile & nerve conduction studies to rule out any pathological cause for the symptoms. Till then, maintain adequate hydration & proper nutrition status, exercise regularly and avoid stress. Take care.
