Your results indicate severe Vitamin D3 deficiency, Vitamin B12 deficiency, and likely iron-deficiency anaemia (suggested by high iron binding). These deficiencies commonly cause fatigue, weakness, bone pain, and tingling sensations. Recommended approach (subject to doctor's approval): Vitamin D3: Weekly high-dose supplements (usually 60,000 IU) for 8 weeks. Vitamin B12: Daily oral tablets or intramuscular injections. Iron: Oral iron supplements (best absorbed when taken with Vitamin C). Specialist to consult: You should consult a General Physician or an Internal Medicine Specialist to get exact dosages prescribed and to monitor your blood levels.
