Open Question: pain radiating from the right waist to the groin area comes and goes but always bearable?

I feel a pain radiating in a vertical line commencing from my right waist going down towards the groin area. Sometimes it acts horizontal along the waits on the right side. I went to a hospital and consulted a urologist, they tested my urine and a sperm sample. Nothing. I went to a gastroenterologist and they tested my stool and blood, nothing out of the ordinary but he diagnosed me with gastroenteritist and gave me some antibiotics. 5 days after taking the medicine, still the pain is there. It is bearable, i can eat normally but its rather aggitating. But sometimes in the morning I feel nausea but won't vomit. Any help is highly appreciated!
