Hello,i am experiencing Si jt dysfunction problem left side with SI itis aswell. physio told me to put cold pack as much as can.i was unable to stand by my own and walk.Severity of pain has been subsided with cold pack and rest.But i am feeling sever tension in my left butt whenever i am sitting and getting up.He told me not to do any stretches coz it will irritate my ligaments again. what should i do to reduce the tension.
