A month ago the <span style = 'background-color: #dae8f4'>veins</span> on
my left arm became very visible from the
wrist to the
vein on the my left side, just below my shoulder, is also visible, it goes down to the heart area
. I asked the doctor and he said its thin skin because of ageing. I'm a bit stumped. Why only on the left arm and chest area
, and why all of a sudden. It seemed to appear after a blood test. My gut says its not thin skin or aging. Does anyone else know about or have this symptom?
