I have shoulder/upper arm pain, it's not severe, but very uncomfortable. My arm feels as if it is being squeezed or there is a blood pressure cuff on it which then causes my palms to turn really red with white splotches on them. It's scaring me and I've tried searching online, but nothing came up. I'm 18 years old, I've had my blood pressure checked twice in the past month and that was normal, I had a blood test done too and that was normal. Please help!
