The feeling of something moving in the right lower abdomen is often caused by the following reasons: first, excessive intestinal peristalsis, because in the right lower abdomen there are colon and small intestine, when the intestinal peristalsis is too fast, it will feel something moving, often caused by eating inappropriate food or drinking too much alcohol. If there is no significant pain, there is no need to worry too much. If the pain is serious, you can apply local heat, if necessary, oral antibiotics or drugs to regulate intestinal flora, and sometimes oral antispasmodic drugs are needed for treatment. Secondly, it may be caused by a throbbing blood vessel. If it is an ordinary blood vessel, there is no need to worry too much at this time, it is a normal reaction, and often it is more obvious in thin people. But some patients are caused by aneurysm, need to go to the hospital as soon as possible to check the abdominal CT, etc. for clarification. If the disease is the case, active treatment is needed.
