restless legs syndrome
"I was given Tramadol after breaking my leg quite badly. At the time the pain was so severe lower strength painkillers wouldn't have been enough but I've now been left with an addiction to tramadol where I've been withdrawing gradually over months and it's now left me with a bad case of Restless Leg Syndrome!  To anyone who has never had this it's a horrible feeling where you can't rest or sleep properly because of the horrible feeling going through your legs, it feels like someone is tickling the inside of your leg and you can't sit still! I haven't slept properly in months now!"
