Dead leg 

Not the same as a Charlie horse- a Charlie horse is a cramp in the muscle and feels different than dead leg. This term is used commonly among recovering drug addicts and others on common medications because a common side effect is a very strange feeling in the muscles(most commonly legs/arms) that is partially relieved by contracting the muscles. This does not work out the feeling as you can with a Charlie horse because it is actually a feeling you’re having, not a physical problem occurring, as the result of the addition or subtraction of unnatural substances in the body.

The heroine addict had such bad dead leg that he couldn’t stop violently moving his legs for hours .

The girl experienced mild dead leg after taking Seroquel for her insomnia and could only truly relieve it by going to bed.
