Hi there. I'd like to answer your question.

I am an Orthopedic Surgeon and would like to help answer your questions. Please understand that the information that I provide is for educational and informational purposes and is not treatment or meant to substitute for being treated by a live physician. I get online once a day and therefore please bear with me if you post and I haven't responded yet. I will in due time. Please do not accept until you have had your question answered in a satisfactory fashion.

If you are 38 then you are young and it is likely that your back pain will resolve. 90% of back pain resolves without surgery within 6 to 9 months. Are you overweight? Are you otherwise healthy? Are you an active individual?

It would be unlikely to have severe bone weakness at your age unless you were a very sedentary person. It is more likely that your back is deconditioned and your core (back and torso and chest) are not as strong as they could be. To alleviate back pain it is important to strengthen the abdominal muscles and back muscles to take the pressure off of the spine.

There is no evidence showing that MBT shoes are good for back pain. However there are many people that use them and get some relief. Typically this means that the back pain is related to posture. I tell patients that MBT are good shoes but expensive and they wear out quickly and it probably would not hurt to use them.

Physiotherapy is an excellent first line treatment for back pain. If you do this for 3 or 4 months diligently you should get some relief. If there is no relief then my suggestion is that you return to your doctor to seek a better diagnosis that "weak bones". An xray provides basic and limited information for a healthy 38 year old. An MRI would give more information. However this is an expensive option and only suitable if your current diagnosis and treatment are not successful.

I hope I have answered your question. Please let me know if there is any other information I can provide. Thanks.
