"my doctor switched me from ms cotin 10 mg 3 times a day to embeda 50-2mg 2 times a day.  i am in continous pain now.  it is not working for me.  i have only been taking it for 3 weeks now and i don&#039;t know if it takes awhile to for my body to accept the change or what.  i go to the doctor next week and i&#039;ll see what he says about it."
