Fentanyl patch side effects

Has anyone had troublesome side effects from being on the Fentanyl patch?  I'm only on 25 mg but I can barely get out of bed, have numbness & tingling in my hands, can't think clearly, have trouble breathing, have a horrible cough, have sores in my mouth, and more... My doctor says my symptoms are not possible on this low of a dose but this is what I'm experiencing since beginning. When I've tried to go off it then I get horrible cold sweats.. I am interested in hearing anyone else's side effects from being on this medicine. Thanks!

Sounds like a serious allergic reaction. I would go to ER!  I will pray for You and keep me updated

I looked it up and it said to get emergency help for what your describing plus it doesn't give like if your only taking this much don't worry! Wow! Please get help
