Sometimes it feels like my right arm is not getting blood circulation. It gets tender in my inner elbow, no tingling like a sleep foot or hand. But extreme discomfort. No matter how much I move it, the feeling doesn t go away. Sometimes it s when my arms have been at 90 degrees cutting hair all day. I m a hairstylist and right handed. Sometimes I wake up and realize I had my arm under my pillow while I was sleeping. Then for hours or mins, it always varies, that pain comes back. Should I see a doctor? I know my job can be hard on the body but I ve only been working behind the chair for 2 years.
