Dear sir/madam, it definitely doesnt sounds like appendicitis
, you would have constant pain in DLQ increasing on pressure, also associated with fever,nausea
. So it can be cramp or u simply injured some of abdominal muscles. You shouldnt be worried except this pain persists and become worse. If you want to be sure you can do abdominal ultrasound
but i dont think its necessary.
Wish you good health.Ivan Romich
