Don't drink alcohol under the pretext of cold, it can cause nerve damage
The human spinal cord is made up of many bones. There is a black disc in the middle of each bone. A type of fluid disc is like nauni ghee. If there is a broken arm or leg due to an accident or if there is a problem in moving the bone, the disc protrudes from between the two bones and squeezes the nerve. In common parlance, this is called an intervertebral disc prolapse.
