Hi my father was telling me that he was experiencing lower right back pain along with some dry heaving and that the pain went down his right groin then he was taking a nap for like two hours and he woke up and felt completely fine just want to know if there something going on with him because it concern me. thank you
Hello, I understand your concern. Pain radiating from the loin to the groin is suggestive of a renal colic.  It can be due to a stone, clot or an infection.  If it is persistent or recurring, I think he should have a urine examination and an ultrasound examination to know the cause. I am available if you have further questions.
