Aching in upper part of legs in thigh areas

Posted by yellowbus

Back in August this year I had an aching tiredness in the upper part of my legs which lasted about a week then vanished and I then felt fine, I could even feel it when I was sat down in the chair at home, but it has now returned since Tuesday of last week, although not as bad as before, its like a dull ache, any ideas please, Im worried it could be something serious.
