Hi and welcomet to HCM.
These are nonspecific symptoms but it may indicate ureteral colic
colic or pancreatiits. You should do at least ultrasound
and basic lab tests to evaluate this. Try to see is there any food that aggravates your difficulties and then avoid it. ALso check your blood sugar because it can cause such symtpoms too. If nothing is found ot these tests then more detailed gastroenterologic examination should be done. Wish you good health.
