i have a vein in my right arm thats raised up, you cant notice it by sight but can feel it pretty easily, its thick, hardened, and is like this for about 3 inches. my other arm isnt doing this... i run a chainsaw for a living and obviously use my right hand to run the throttle so that hand is always squeezing, im 26 years old 6'1" 198lbs in pretty good shape and always physically active
and i know how ARFcom GD is, so ill just throw this out there- im not a needle user
no track marks here
what would cause a vein in my arm to be larger and hardened ? i noticed it last night and its still an issue
