I've noticed that after 1 or 2 days of moderate adderall use (20-60mg daily) my lower back is sore. Anyone know what the cause of this is (I'm thinking kidneys perhaps?)
I *know* its the adderall because if I stop, it goes away in a day. If I redose, it comes back. Couldn't be spine/bone, perhaps my muscles tighten from the amphetamine? But why only lower back? Or is it secretion of the drug through kidneys?
And also, is it something I should worry about (as in I should not be taking adderall because my body responds this way).
