Dear Friend. Please elaborate your problem. What do you mean by loosing circulation? Are you talking about tingling in hands and feet? Or its Numbness? When you lie in an inappropriate position sometimes your nerves get compress and you feel that the portion is numb and there is tingling, and it resumes to normal in few minutes. If this is your problem then its normal, nothing to worry, try to maintain correct position. But if you feel weakness in your limbs, you feel there is continuos tingling or numbness, or you are having difficulty holding hands or walking, then yes you need an evaluation.
