What is the pain in the middle of the sole?

Middle sole pain may be caused by muscle strain caused by standing for too long and walking for too long. It may also be caused by lumbar disc herniation. When the nerve root is compressed, it will cause pain. In addition, middle sole pain may also be caused by cubital tunnel syndrome. When the pressure in the cubital tunnel increases, it will cause compression on the brachial nerve, which will be accompanied by middle sole pain.
