Hello dear, The symptoms as mentioned in your post can be due to: 1. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium, Magnesium, etc. 2. Any fluctuation in blood pressure levels 3. Altered blood sugar levels 4. Inadequate hydration & nutrition status. 5. Peripheral neuropathy. Symptomatic relief can be obtained with nervigenic agents (like Vit B6, B12, Folic acid) & multivitamin & mineral supplementation. Investigations like complete blood count, estimation of blood pressure and blood sugar levels & nerve conduction studies will be helpful in clinching the diagnosis. There is no need to worry, you will be fine. Meanwhile, maintain adequate hydration, take a healthy balanced diet & avoid stress. Wishing a good health. Take care.
