A buzzing feeling on front pelvis, on left side of pubic area? i might have si joint prob or pirformis sydrome, could any of these cause it or not?

Pain: Less likely to be SI joint and not at all likely to be piriformis syndrome. Sometimes the SI joint pain may radiate to the groin area but would feel like a deep dull ache. It would increase while bending forward and esp getting out of a chair. There may be tenderness in the back. Please inform us of any aggravation and relieving factors, any other symptoms. That may get you better answers.
