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.. good luck.
