hi my mother is suffering from knee gap on her both legs. she is a kidney patient so she can not take pain killer..family doctor has adviced not to take pain killers. she has suggested not to go for knee replacement operation because of her weight she is of 85 kg and has BP problem also her one kidney was very small since birth but it has shrinked and has stopped working
First consult a Nephrologist for evaluation of kidney disease and steps need to be taken to prevent further kidney damage like control of high BP. Most of the painkillers need to be avoided in kidney patient. But still there are some painkillers which are safe in kidney disease. Consult your doctor regarding this. Take care
