Hi Thanks for your query. After going through your query I came to know that your wife is suffering from chronic backache. It may be due to vitamin and trace element deficiencies specially vitamin D and vitamin B 12.She can get her vitamin D and vitamin B12 levels and if found low she can take its suppliments of vitamin B12 and D3You need to done MRI to rule out other causes. Back exercises, neurotropics such as mecobalamine and analgesics such as Ibuprofen give relief. Avoid long continuous standing. As sometimes pain is severe so she is also advised to exclude kindey related causes by ultasound of kidney and abdomen.You can discuss with your treating Doctor about it. I do hope that you have found something helpful and I will be glad to answer any further query. Wishing her good health. Take care.
