Muscle Problems
You might not have infections, but you can still suffer from flank pain due to problems with your muscles. The pain might not come directly from the flanks but from your chest, back, or stomach muscles. Muscle injuries due sprains and strains, overuse, a sedentary lifestyle, stress, and tension commonly cause muscle pain. The pain could be temporary because you stayed in a physically stressful or unusual position for a long time.
The pain you feel in your flank could be from one side where the muscle was injured. But if you maintain a sedentary lifestyle, you can feel flank pain on both sides. Sometimes, the pain can occur on your upper body’s right or left side.
The most common cause of flank pain is muscle injury. The pain you feel could be intense. However, you should know that the pain’s intensity does not indicate the injury’s severity. Other causes of flank pain include back problems, structural problems and fractures in your spine, arthritis, degenerative disk disease, pinched nerve, and herniated disk. These strains usually lead to painful muscle contractions in the lower back or flank.
