<s>[INST] I had stomach pain in the lower right side of my abdomen that felt like contractions.  I have had a complete hysterectomy so it is not pregnancy-related.  The pain has subsided but my right side feels very tight and like I could have another cramp/contraction at any time. [/INST] The most common cause of right side lower abdominal pain is acute appendicitis.I would advise you to get ultrasound abdomen to rule out appendicitis.  For cramps you can take any antispasmodic like Tab Meftalspas. </s>
