I am 67 years of age and I have a difficult time sleeping at night. Just as soon as I lie down and try to sleep I start getting thigh pain on the side that I am sleeping on, then as soon as I switch sides the pain starts on that side. I toss and turn all night long and do not ever get a good nights rest. When I get up out of bed my legs feel very heavy from the knees down and I feel a lot of pain on my shins. Once I start walking around I feel no more pain, until I decide to sit for lunch or dinner and upon getting up I have difficulty again until I walk around again. I have been taking magnesium citrate but it does not seem to help. I hope you can suggest something for me.
