Blood Test Sample

It's been few days since I have pain in my neck. Actually, the pain is in the back side of my neck. I don't know why I have this pain. It can be that I sit too long in wrong position when I am using computer. But I am more worried if the pain is something that has to do with my blood pressure. I think I want to do blood test sample very soon. I want to know if my blood pressure is still in a normal level or there is something wrong with it. I don't want to be late to know it if there is something wrong. The earlier the better, I think I should put it that way.
But I think I need to do fasting first for few hours before I get blood sample test. Not sure about it but I will check it to the laboratory before I plan to go there.
