Hello!
Welcome on Healthcaremagic!
Your symptoms could be related to different possible issues : a metabolic disorder like
thyroid dysfunction, chronic inflammation or
anxiety. A
hormonal imbalance, can not be excluded either, especially considering the fact that your symptoms repeat each month at the same time. I would exclude any neurological disorders possible related to this clinical situation.
Coming to this point, I would recommend consulting with your doctor for some tests:
complete blood count for anemia, blood electrolytes, PCR for inflammation, thyroid hormone levels for electrolyte imbalances, sex hormone levels, fasting
glucose.
If all these tests result normal, it would mean that nothing serious is going on.
Hope you will find this answer helpful!
Best wishes, Dr. Aida
