Mending a herniated disc at home begins with relaxing the muscles through over-the-counter anti-inflammatory medicine, and the application of heat and/or cold therapy. Heat can relieve the muscles of tightness and spasms by increasing the blood flow and improving the elasticity of connective tissue. Cold therapy reduces inflammation and acts as a painkiller in the local area that is causing the discomfort. Together, conservative treatments like these along with rest and prescribed exercises can bring comfort for those with a herniated disc.
