He was also taking IB profen and medication for hypertension .
well you're not giving us alot of info. Has he had a renal panel done with bloodwork? What is his GFR, creatine, etc? He needs to not take ibuprofen or any anti inflammatories as they are filtered through the kidneys...not good. I don't know if the scoliosis is affecting his kidneys tho. It could be his medications, diet, etc.
I don't know any specifics. Just what I wrote. You are correct, his doctor told him not to take ibuprofen, blood pressure meds, drink more water. He is having some more test run though.
He told me that the doctor routinely checks his blood due to his medicines for Hypertension. So, I just know blood test were done.
