I had a blood test about five, four days ago on my left arm. The thing is, it hurts when I straighten it out like my my muscles contract. And it gets a cold rush feeling when I hold it in the air too long.
I have pretty small arms and not allot of muscle, but their huge in length.
I forgot the name of the part, or the name of the vain but its around the elbow area.
It hurts mostly in the soft tissue part of the elbow.
