Hi. My father is 57 years old having back pains since several years. He is not having any other health problem like BP, diabetes etc. We had consulted many orthopedic, homeopathic and ayurvedic specialist several times. They had all the necessary tests on him. But all results are normal. X-rays, blood test are also normal. He have no calcium deficiency as well. Then what would be the reason? Due to such pains he dose not seems fresh and happy. What should be done is such a case?
