Restless Legs Syndrome
"My story is just so similar to so many on here. I have had severe leg pain in my calfs since I was about 10. I would wake up crying and when presented to a Dr I was told they were just growing pains. In my early 20s it got much worse.  The pain was unbearable and the RLS drove me crazy with the not sleeping I was loosing my mind. I was given some tramadol after some dental work and immediately felt the effects of the pain being gone and the shaking and twitching was completely gone.  I noticed that when I stopped taking it, by the next day the pain and twitching would return.  My Dr had no problem prescribing until they made it a controlled substance."
