I think these questions would be good to ask your doctor and let him/her know what side affects you are having. It's hard going from one medication to another. That is what I am going through right now. After reading your post I don't know if I want to take Cymbalta although I know everyone is different. Just my opinion.....I think the difference between normal and numb is: normal you feel alright, pretty even kilt and numb you feel nothing, just numb. Good luck at your appt. today! Let us know what happens.
