Hello dear, The symptoms as mentioned in your post can be attributed to: 1. Reduction in blood sugar levels (Hypoglycemia). Relief of symptoms on intake of chocolate indicates towards the same. 2. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium, etc. which interferes with blood formation & nerve conduction. 3. Any fluctuation in blood pressure levels (Hypo/ Hypertension) 4. Any pathology in the vestibular apparatus in inner ear (it is associated with maintenance of body posture & balance) Symptomatic relief can be obtained with maintaining optimum blood glucose level. In addition, you can take nervigenic agents (like Vit B6, B12, Folic acid) & Pantoperazole (to be taken 30 minutes before meals). If it still persists, then you need to consult your Physician/ ENT Specialist & get a complete clinical examination done. Investigations like estimation of blood pressure, blood sugar levels, serum electrolytes & vestibular function tests will be required to rule out any pathological cause for the symptoms. There is no need to worry, you will be fine. Till then, maintain adequate hydration & proper nutrition status and avoid stress. And also take precautions of getting up from bed slowly & avoid sudden head movements. Wishing a Good Health. Take care.
