My father is nearing 78 and had knee replacement suregery three months ago. Prior to the surgery, he was taking hydrocodone for
about a year...four or five a week at start and as many as four or five a day right before his surgery to relieve knee pain. Post operative, they placed him on 20mg oxycontin twice daily (w/ Darvon for breakthrough pain).
Sixteen days post operative he began to feel sick...
nausea, trembling, depression, palpitations of heart, sleeplessness.
