Herniated discs often do not need to heal at all. That is because most minor and moderate herniated discs are not painful or problematic in any way. They merely exist. In fact, herniated discs are a common side effect of normal spinal aging.
When the herniated disk is located in your lower back, it causes irritation to the nerves and results in numbness, pain and weakness in your leg below the knee, your thigh and your buttock. Treat a herniated disk with gentle exercise (don't stay in bed too much as it can make the problem worse), cold packs then heat packs, and over-the-counter pain medication.
