A muscle pull in the right side of the body is often confirmed by an X-ray and an evaluation of symptoms by a physician. Abdominal muscle strains usually carry symptoms of stiffness and discomfort, muscle spasms and pain when flexing the area, according to NYU Langone Medical Center.
Swelling, bruising and tenderness to the right abdominal area of the body may also indicate a muscle pull, explains NYU Langone Medical Center. An abdominal muscle strain in the right side indicates a full or partial tear of the small muscle fibers in the abdomen that make up the core muscles in the body.
An evaluation of activity can also determine if a muscle is pulled on the right side of the body, notes NYU Langone Medical Center. For example, if a person participates in excessive exercise or activities the muscles were not prepared for or enacts improper techniques and a lack of stretching while playing sports, a muscle pull can occur. Lifting heavy objects and sharply twisting the body can also cause muscle pulls in the right side of the body. Treatment may include physical therapy; application of heat and ice packs; over-the-counter medications to reduce inflammation and pain; and rest.
