Re: Could this be Arthritis???
Is it like a cramping sensation at all? If it's not arthritis it could be some kind of vitamin deficiency, like B12 for example. Even though you take calcium and vit D, you may be a little low on B12, unless you know you are not. I'd go see the doc if it doesn't go away. There are various types of arthritis and people feel it differently, so no way for me to tell for sure in your situation. For example, the arthritis in my neck feels different than the arthritis in my hands and forearms.
