What Causes Twitching Under Right Rib Cage But No Pain?

The body’s muscles sometimes twitch or spasm without causing any pain. This is called fasciculation, and it happens when a group of muscle fibers contracts on its own. In the area under your right rib cage, such twitching is usually harmless. It might occur if you are feeling stressed, tired, or if you haven’t been getting enough of certain electrolytes like magnesium or calcium which help your muscles contract properly. Managing stress, staying well hydrated, maintaining a balanced diet, and getting good sleep may help reduce the frequency of twitching episodes. Often, these twitches come and go on their own and do not cause discomfort or pain. However, if you notice that the twitching becomes very frequent, lasts for a long time, or is accompanied by other concerning symptoms, it is a good idea to discuss with a healthcare professional.
