Leg pain at night - can't sleep

Anyone else get really bad leg pains at night? It's like a dull ache through both legs. Kinda feels like I need to stretch them to get rid of the pain but it doesn't help. When I was younger Mum called them growing pain. Now I'm pretty sure it's restless leg syndrome (according to google) I don't see any point in going to the doctor there is no known cause or cure. Please tell me I'm not alone. And help me get to sleep :(
