It is important to address these long-standing symptoms. Irregular cycles accompanied by severe leg pain can sometimes be linked to hormonal imbalances, conditions like PCOS, or pelvic issues. Because these symptoms have persisted since 2015, I strongly recommend consulting a gynecologist for a proper evaluation, which may include blood tests and an ultrasound. For temporary relief of the pain, generic over-the-counter pain relievers like ibuprofen can help. Once a proper diagnosis is made, a doctor may prescribe targeted treatments, such as generic oral contraceptives, to help regulate your cycles. Please avoid starting any hormonal medications without a professional medical assessment.
