Extremely painful,aching,stiff legs from below knee?

[Bluebellina]

Does anyone have any clue what could be causing this.I am 47,not overweight etc and am really suffering with this at the mo. Its like a really aching,tired,stiff feeling-sometimes worse in one leg than the other.I get relief if I take the weight off them and elevate them but it is becoming very problematic lately.Inflammatories also relieve it periodically. I do have varicose veins on my legs but they are not severe looking and find it hard to believe that they could cause this level of discomfort?Or could they?I think I will make a dr.appointment next week anyway but I was wondering if anyone else has had this and knows what causes it?

I have had this recently too and was thinking of making a DR's appointment. Mine are not painful but are uncomfortable, tingle and ache. I play sports, bike and walk but thisdoesn't seem to have any bearings on my lower legs. I wondered if it was because of low iron . It is very irritating though.
Best get a proper diagnoses from the DR I suppose.
Good luck.
