Hi,
Thanks for writing in.

There are 5 small bones aligned on top of each other in the lower back which are together called the lumbar spine. There are soft discs which are spongy structures between 2 bones. Nerves which originate from the spinal cord pass through the holes between 2 bones and then supply the legs.

When there is overgrowth of the bones or the disc gets degenerated then it presses on the nerves and causes pain. Numbness is also due to significant pressure on the nerve roots in the neural foramina.

It is required that you get a MRI scan of lower back done if you have not got one done and your symptoms of numbness and tingling are recent. This will help to know if the nerve is getting pinched in any location. The doctor will decide the treatment after going through the findings of your MRI scan. Please avoid heavy physical activity and get nerve study done as recommended. Please do not worry.
