I have 4 children and by the time it's 10pm my legs ache in pain and i take ibruofen every night?

Not good: Too much Ibuprofen is associated with heart damage. Have you tried stretching over the course of the day. This may relieve some of the leg pain at night. See a physical therapist or find some good leg stretching exercises on the internet. The easiest is putting your leg up on a chair and leaning, not bending forward. Also try getting down on one knee and leaning forward. Do these for ten seconds.
