I took Fosamax 70 mg once a week for 2 months. I quit taking it 2 weeks ago due to severe elbow pain, pain in shoulders and neck and right big toe is numb with electric pain. The first 2 days after taking dose I had headache and flu like symptoms. My doctor was not much help and wants me to stay on it if I can stand the side effects. I can only hope this goes away. Does anyone know how long it takes for the pain to diminish after stopping this terrible drug?
