What are possible causes of chronic lower back ache in a weightlifter?

Thanks for posting your question – it’s a really interesting one and something I am sure that is shared by many others. As Dr Sean has mentioned, flat feet are common, but they should not necessarily be regarded as a “problem” per se. If you look at most Asian patients, low arches are the norm. There is often a line of thought that flat feet are the root of all pain and injuries. In fact, pain can be attributed to different factors such as: Your chosen activity Your training load Overall strength Whether any equipment you are using is appropriate for you.

Thank you for your questions. I agreed with both Dr. Sean and Dr. Dinesh that your pain is likely "discogenic", meaning that it is coming from the disc, which is the cushion in between the bones. There are also a spectrum of a "slipped disc", only when the slipped disc is very severe and compressing onto the nerve then you will develop tingling sensation or sciatica. Of course we don't want to wait until then before we do a thorough checkup on you, I'd recommend a MRI scan for you to investigate the actual cause of the pain and the severity of the condition.
