Brief Answer: Can be due to hormonal disturbance. Detailed Answer: Hello, Thanks for trusting us with your health concern. Since your symptoms have returned after 3 weeks, it is less likely to be due to a post infectious syndrome. The symptoms that you have can be due to a metabolic problem, hormonal imbalance, thyroid problems, vitamin D3 deficiency, electrolyte imbalance, depression, anxiety, etc. Sometimes a fluctuation in calcium, potassium or magnesium levels may lead to this kind of thing. This would be easy to treat with an over the counter multivitamin as well as a supplement of calcium with vitamin D. The symptoms should respond within 7 to 10 days. In the event that this does not occur, I suggest you visit with your primary physician for a complete physical exam and possibly some blood work as well. In the meantime, try not to worry about this and focus on maintaining good health with diet, fluid intake and exercise as well as adequate sleep (7-9 hours per night). Please feel free to discuss further. I will be glad to answer the follow up queries that you have. Wishing you good health. Regards. Dr. Rakhi Tayal.
