What is the cause for tight pelvic muscles?

Question

I went to a physiotherapist who massaged my posterior pelvic muscles with his elbows and said they were tight. I was wondering, could tight posterior pelvic muscles be from a hip misalignment at the sacroiliac joint that the muscles are compensating for? Or are there other causes?

Answer 1

so they said you have a tight bum?

I wouldn't take that as an insult.
