I was given Fentalyn during a cardiac cath and start shaking very hard.The physician gave me Benadryl to stop it. I was given Fentalyn during a colonoscopy the physician denied any shaking. Later I started shaking--The ER told me I had Parkinson(Parkinson does't develop overnight). I am about to have surgery again. Fentalyn was the only drug in noted to have been used in these procedures. Could Fentalyn be the problem?
