What causes chest pain due to costochondritis?

Costochondritis, or costosternal syndrome, causes pain and tenderness without clear trauma or lung infection. If no specific cause is identified, consider potential factors like vitamin D deficiency or issues related to the liver or gallbladder. For natural remedies:

- Betaine hydrochloride before meals (3-5 capsules)

- Purified bile salts (morning, after lunch, and afternoon on an empty stomach)

Consult a healthcare professional before starting supplements and ensure thorough medical evaluation to exclude other conditions.
