I have an uneven pelvis and not sure why.. few questions

[user58374]

Can the piriformis syndrome, groin injury, or sciatica have an impact on my muscles in my hips cause my pelvis to go out of place? My pelvis is raised on the left side... The same side where i experience pain. The hospital i went to only went through X-rays and did not want to perform an MRI because they told me that getting a shoe lift for my right foot would fix the problem... But its been months and the shoe lift hasnt.. Which makes me believe that whatever muscle movements in my hip from the conditions im guessing i have is preventing my hip from moving back... If one of those diagnosis' are possible with the muscles around my pelvis moving, is surgery an option for any of them all? I have a hard time with exercise. When I exercise, i get relief right after but then for the next 3 days i feel pain and stress where i've exercised.
