My mom has a gleeoblastomia brain tumor and has recently had treatments. She has been on a high dose of steroids whichnhave had some side effects. She is experiencing leg and foot edema. The doctor did prescribe something to help and she took the first pill today. Today her legs started to leak or weep a pinkish fluid. I had initially recommended she stop drinking soda and drink a lot of water. Will this cause her more problems?
