SPD pain

I’ve had pubic bone/pelvic/hip pain for the last few months and have been seeing a chiro and physio and it was getting better/staying pretty stable.

Yesterday I had to run after my nephew really suddenly to avoid a dangerous situation. Ever since my pubic bone and the bottom of my belly have been incredibly painful. Baby is still moving normally.

Has anyone experienced anything like this? Did it get better again in time? I feel like I can barely walk or stand.
