Monthly pain for 20days around my period

For the past year, I’ve had intense, recurring leg pain which intensifies during my menstrual cycle, starting a few days before my period and lasting around 20 days. This began after I had dengue last year, and despite seeing over 20 doctors, haven't found a diagnosis. This month, for the first time, the pain has shifted from my leg to a severe headache that’s unresponsive to typical pain meds. I started lifting weights two months back, so I believe my legs are stronger and hence this time, the pain shifted to a different location. I’ve also been experiencing sudden, excessive hunger every hour, and if I don’t eat, the headache worsens. Given the timing around my period, I’m wondering if this could be hormonal or due to a deficiency, especially since managing hydration, diet hasn’t helped. I’d like to know if testing for hormonal imbalances or deficiencies could provide insights, and if certain vitamins or minerals could help with these symptoms.
