Hi welcome to H.C.M.Forum. the veins would have become atherosclerotic due to cholesterol
. or there may be diference in coagulation factors. your age is not so old to cause such changes.
i advise you to consult a surgeon for diagnosis. you may have to under go some tests like TC, DC ESR
, BLEEDING TIME
, CLOTTING TIME, LIPID PROFILE
i advise you to eat more of green leafy vegetables, cereals, fruits& juicse to enhance repair process
wishing for an early recovery.
