I noticed for the last couple of months my lower legs and my feet ache after doing hardly anything.
after walking 5 minutes around the house or walking round the garden my legs just ache. they ache after i havent done anything for example sititng down and getting up again
I think my father had a similar problem when he was my age (on going 18) and Im not obese or over weight and i dont smoke and drink scarcely.

Secondly

after eating, i feel automically drained. Eating pasta or something bulky like potatoes gives me a two minute "buzz" kind of and then all i want to do is sleep (Lol totally bizarre) but scary!
Is this sign of something more serious?

Thanks a trillion :)
