Started Having Back Spasms In The Middle Of My Back,

Started having back spasms in the middle of my back, right below the bra line. It comes out of no where when I'm sitting, standing, and reaching. I have good posture and sit up straight. I carried some groceries in up the stairs (maybe too many at one time), but I did not feel the pain at the time. When I sit down, it feels like I'm sitting on my groin area. I feel a slight headache that seems to trickle down the side of my neck. I also have braces.
