young female of 23 and suffering from a severe stiff spine for the past three months I am 23 yrs old, female, suffering from severe stiffness at the spine, right sacroiliac for the past three months. I am not being able to sit with my legs folded and facing an obstructed feeling in the right sacroiliac when bending forward. I experience a stiffness from just above the pelvis, to the center or sometimes to the left of the back, 24x7. There is a constant bow-string effect on my spine, as if an unwanted force is exerting pressure on my spine and giving the stomach muscles an uneasy feeling.....please help me.......
