What Causes Severe Pain In Feet While On Oxycodone, Buspirone And Duloxetine?

my best friend is on several medications. She and I as well are concerned as she is crying often-is also moody, angry-stays in bed in pain quite often-I can tell the pain is real much of the time-but question other times. My friend is 73 years old- Medication prescribed is oxycodone apap 7.5 325 mg 4xday==Buspar Buspirone HCL 30 mg 1 by mouth 2 x day Gabapentine 300 mg 3 x a day lorfaapam 1/2 mg 2xday=Sertaline 50 mg 1 @ bedtime- duloxetine 60 mg 1 in morning - resperalone 1 mg 2 @ nite only derilant 60 mg 1 in a.m. lisinpril 40 mg 1 per day carvedilot 2 per day 6.25 mg Phenegren 25 mg 1 every 5 hrs. -Risperalone -1 mg @ night only ====My friend is getting worse. She wants to stay in bed all day-she does complain of pain in her feet= Usually though she is often rude, however she does attempt (at times) to listen when I tell her that she has many friends and family who love her) although most don t come often or stay only a short time when they do as she makes them feel uncomfortable. I told her about this site and she encouraged me to question as she feels she is on more drugs than necessary and fears some may be interacting with others. Thank you
