Why am i having compression fractures in my spine along with pain in pelvic area, muscle spasms in feet, legs, and tendon area?

See your doctor: All those symptoms appear unrelated. It is very unusual for someone of your age to have spinal compression fractures without significant trauma. So if you really do have compression fractures, you need to find out what is causing those fractures? You will need to undergo a physical exam, and various diagnostic work-up, to understand what's is causing these issues.
