Please do not self-medicate. Chest pain is a potential medical emergency that requires immediate evaluation at the nearest emergency room to rule out heart issues. Combined with bone pain and tiredness, these symptoms could indicate serious underlying conditions such as cardiovascular disease, severe anemia, hormone imbalances, or bone disorders. A doctor must perform diagnostic tests, including an ECG and blood work, to determine the exact cause. Do not take any pain relievers or other medications until you have been evaluated by a healthcare professional.
