I'll add to this, pay attention to your chairs. I originally thought my injury was in my leg (that's where all the pain was). It had lasted 3 weeks before it was properly diagnosed. After being put on steroids and starting PT I saw quick improvement, but I plateaued after a couple weeks. I realized that my chairs at home were the problem after I spent a few nights sitting at my kitchen table working on a project. That chair put me in a posture that helped a lot. Switched back to another chair for a couple nights, I got worse, switched back, I got better. So try different seats for a few nights each, you may find that the ones that feel comfortable to sit in are actually hindering your recovery.
