Did an injection for my shoulder... it lasted about 4 ½ years before I had to get surgery... just have to be cautious as some of the things they use will make tissue brittle and if you need surgery then you're kinda screwed... or they have to go more extreme. PTs suck unless you get one that is occupational, and will focus on the things you need to do. I've had 7 recommendations to get surgery... I've actually had 2... the other times I modified routines, habits or diet.
I literally threw away all my shoes and went strictly zero-drop, wide toe box. No heels relieved a lot of low back and knee pain. On the occasion I have to go with conventional footwear, I saw the heels off...
Caveat Emptor
Good luck... hope you get some relief
