My sis believes its withdrawels from his dilaudid meds. He ran out. the tremors subsided but because of his multiple health problems including multiple myeloma, I am concerned that these tremors may have been a sign of something else. He also has COPD. He's 58. She and I are all he has....he won't let me help because I "smother" him at the drs office by bringing up issues like this. Should I just back away? My sis had a stroke three weeks ago, and also has high blood pressure, scoliosis. What should I do?
