My Husband Had Radiation Beads Via Catheter Into 1/3 Section

My husband had radiation beads via catheter into 1/3 section of his liver matastisized tumors 11 days ago. He is still suffering from pain, exhaustion, nausea today. His good liver function was marginal at the time of the procedure. Are his symptoms lasting from the procedure or are they perhaps because he has now gone below the threshold of good functioning liver to not enough functioning liver? Low grade fever and no appetite are also symptoms still. How long can this last from a treatment. This is far more severe recovery than described, therefore, I am concerned that we are dealing with a bigger picture.
