My friend he is Balnise has big varacoise veins in the back of his legs, recently gave him bad pain while in the snow in France, personally I think the veins are linked to parasits, what is your opinion? He mostly lives n a damp area washes and drinks from the polluted creek that runs thru the property, he also has bad lower back pain , he is very skinny but has muscles due to surfing and hard work... What should he do?
