<s>[INST] Two weeks ago I had pain in my lower abdomen, it felt like bad gas, but was a nagging ache when I walked, coughed, laughed, etc.  It went away within about five days.  Yesterday the same pain started again. Hurts to walk, climb the stairs, cough, laugh or sneeze.I had a hysterecomty about a year ago, so I know its not any problem with the reproductive organs. Any ideas?  Thanks. [/INST] Hi welcome to Chat Doctor forum.  You have got lower abdominal pain, on walking, coughing, laughing, for 2 weeks. You got hysterectomy done one year back.  It may be due to urinary tract infection, or stones in the urinary tract. Rare possibilities are surgical hernia, etc. I advise you to consult a surgeon for diagnosis and treatment. You may need to get M.R.I. besides other routine tests for confirmation.  Best regards. </s>
