Persistent nerve pain after 2 weeks of taking Rejunex CD3 may occur for several reasons. Nerve healing is slow, and vitamin supplements alone often take longer to show effect. The pain may also be due to underlying conditions such as diabetes, nerve compression, injury, or other medical issues, rather than a vitamin deficiency alone. Additionally, individual absorption or dosage issues can influence effectiveness. Clinically, it is important to evaluate the underlying cause with appropriate tests and consider specific neuropathic pain treatments alongside supportive supplementation.
