Many patients with back pain, leg pain, or weakness of the lower extremity muscles are diagnosed with a herniated disc. When a disc herniation occurs, the cushion that sits between the spinal vertebra is pushed outside its normal position.

Muscle strains are classified by a grade scale from one to three. Grade 1 strains are microtears that allow full functionality. They are caused by minor trauma, such as a hard workout. When you experience muscle soreness, you have a grade 1 strain. Grade 2 strains are more detrimental to the functionality of a muscle. This is a partial tear to the muscle, causing a noticeable decrease in strength output. When you experience muscle pain beyond normal aches and soreness, you likely have a grade 2 strain.
