Welcome to HCM!
You haven't mentioned Right side of "what" like abdomen/limbs/face/chest/ whole body is having the problem..nor your age/sex..
But because you have mentioned no vomiting
, I suppose its right side of your abdomen that is cramping..
You should do an Ultrasound
of whole abdomen, X-ray KUB, RFT, urine (R/M).
Physical examination by your doctor is important.
Till then, with your doctor's advice, take antispasmodics, analgesics, muscle relaxants & antacids.
Wish you a healthy life.
Take care. Thanks.
