What Causes Tiredness Along With Pain In Leg And Dizziness?

I was wondering if I should see a gp? My symptoms are as follows, I am extremely tired all the time, my skin is sore to the touch, feels either very hot or like a bruise. I get extreme leg/foot pain. I can t sleep for more than 3 hrs without waking, I take a long time to fall asleep. I m 51 year old female I am going through the menopause. I get dizzy spells, and very low concentration levels. Been like this at least 6 months, although the sleep thing has been for several years.
