35+5 extreme pelvic pressure

It is 89° feels like 100° where I live. Took my dog out with my parents and their dog for a mile long walk down an even sidewalk in our town.

Came home, drank water and sat down to relax.

Well...I am feeling some new pains and pressures.

I work at a Walgreens as a manager and I walk/stand my whole shift. Nothing new there.

But now my hips and pelvis feel like one solid pain unit. It hurts to twist or bend or sit or stand. No contractions that I can feel. Just a ton of really uncomfortable pressure/pain. Pretty consistent.

Any input?
