My legs seem to tense up and i end up with lots of muscle knots. this reoccurs daily. any ideas why? also have nocturnal bruxism.

Stress!: The fact that u are having nocturnal bruxisms, along with your tensing legs, it sounds like your symptoms are related to significant stress, and your inability to address it. I see that u are on meds for ADHD and depression and/or anxiety. Are u seeing a therapist for Cognitive Behavioral Therapy to help address your stress/anxiety? I not - go. Would also recommend exercise and massage.Take Care

Concurrent: Your problems may be concurrent but not associated. Discuss leg cramps w your Physician. May be potassium level problem. Discuss bruxism with your Dentist. May need a night guard.
