text: leg pain, like a tight feeling, help? when i sleep, i sometimes get this pain in my leg (also, sometimes, leg and lower). its like a tight muscle kind of pain, and it gets worse when ever i move it. but after a while it goes away and comes back. and sometimes it would get alittle better but it feels like the pain is still there. if your not getting the proper sleep/rest it can cause muscle cramps........are you getting the required sleep?
