Dear friend, welcome to HCM.
does the pain move from the mid back (flanks) to the groin?
do you have sweating/ nausea/ vomitting?
do you have fever?
if it is colocky ( twisting pain, comes and goes ), it is likely a colic
and you will need evaluation , lab, USG etc. to look for stone disease.
also there are many differentials in the abdominal pain
. pl. see your Doc in person and get checked.
I hope to have helped you. pl. keep me posted on the progress..
