"Took for 5 months.  First 4 months great.  Then got intermittent tingling and numbess in arms.  Over next month tingling went to constant throbbing.  Pain shooting down right arm.  Stopped pill.  It has been 7 days and left arm back to normal.  Right arm slight numbness and some discomfort but getting much better.  Be aware of symptoms!"
