Welcome to health care magic.
1. The
lower abdominal discomfort can be due to many causes, commonly
low back pain / discomfort due to spinal degenerative causes - not associated with burning sensation while passing urine.
2.Other possible cause could be PID -
pelvic inflammatory disease - which needs a pelvic ultrasound for evaluating the cause.
3.The cough associated with the abdominal discomfort is due to
musculoskeletal pain due to strain on the muscles while coughing.
4.The painful area on touch in the inguinal region could be an
enlarged lymph node - which can arise due to any infection / inflammation it can be localised or systemic.
5.Finally i would recommend to see your GP and get examined, pelvic ultrasound will give some conclusion to the condition.
Good luck.
Hope i have answered your query,
any thing to ask ? do not hesitate to ask.
