My ADD symptoms have decreased significantly with my current rx, but I am beginning to experience muscle stiffness and 2-310 pain along my neck and spine in the late afternoonevening. I was curious to know if this is a common side effect associated with Adderall and if so, are any common tx options ie switching from amphetamine salts to name brand Adderallalternative ADD medicationsetc. I am scheduled to meet with my psychiatrist next week, but thought in the meantime I d see what the medical community here had to say.
