Bad SI joint pain… will it get better?

Maybe. Maybe not. Need more info.

I’m struggling with that currently, along with my lumbar stenosis and other spine issues. So far I’ve read that physical therapy may help.

maybe, maybe not. You will need to see a doctor for an evaluation. Had mine most of my life. hip and back surgery fixed it. but then I got older and it comes back as I need another back surgery. Mines from a scoliosis.
Get out there and exercise and you'll find out!

I went many years SI joint pain, Doctors always thought I was "drug seeking"they would say..get some rest ICE/HEAT and Motrin. Finally diagnosed having Ankylosing Spondilitis. at VA Denver, I was prescribed a Biologic and found relief. Does the pain get better with movement and worse at night..? If yes it might be worth asking your doctors. A rheumatologist specializes in Ankylosing Spondilitis diagnosis....I hope you don't have AS, but most Doctors miss it. Otherwise known as (axSpA or Spondyloarthritis)

I have a bad SI joint that caused me severe pain. I received two steroid injections about ten days apart, and that provided me with complete relief for a decade. You might consider trying that!
