A muscle strain occurs when muscle fibers are stretched or torn, often due to overexertion or improper movement. Common causes include lifting heavy objects, sudden movements, or sports injuries. Symptoms typically include pain, swelling, and limited mobility in the affected area.
Treatment for a muscle strain usually involves rest, ice, compression, and elevation, often referred to as the RICE method. In more severe cases, physical therapy may be recommended to help restore strength and flexibility. Most strains heal within a few weeks, but severe strains may require medical attention.
