Female, 29 -- 175 lbs -- 5 3 Earlier I felt a dull pain & some heaviness in my left arm. I was carrying a bag & it almost felt as if I would drop it if I didn t change hands. I ve just noticed the veins in my left arm around my inner elbow area (where I ve been feeling the pain) are really pronounced. My right arm doesn t look like this and this is unusual for me. When I had my kids the nurses had a hard time finding my veins. Should I be worried?
