My father had some mild renal dysfunction due to a couple of MRI-Contrasts he had, and in combination with a bad diet, his kidneys were acting up a year or two ago. WIth some changes, his renal function is pretty much back to normal (88 % according to his dr which is good). He sees a nephrologist periodically who is of no help now. His issue is severe kidney pain when he takes certain medications, like an antibiotic or pain meds. He has a fungal infection in his sinuses and was taking an antiobiotic that seemed to help, but his kidneys 'light up" as he calls it, and it is unbearable pain. He also thinks his recurrent back pain is kdney pain, though his nephrologist thinks the pain is coming from something else. What he is troubled by though, is all it takes is some bad food or certain medications and his kidney pain is severe. It goes away once he stops the med, but he is worried that one of these days, a severe infection will "do him in" since certain antibiotics both his kidneys. Is there a medical term for this? Does anyone else have kidney pain with certain meds, etc?
