Generally antiinflammatories (ibuprofen or naprosyn), heat/ice, rest (no making beds, cleaning stoves, or using a sledgehammer to pound your truck's frame back into shape). PT is oftentimes helpful, but I think you said you'd been doing PT.
It would probably be a good idea to get to the doctor when you can so they can physically evaluate you and decide if you need imaging or further treatments.
All reasonable. I was allotted 25 physical therapy appointments but had to stop them because of no transportation. Really just after 7 appointments with them I went from feeling like crap to actually feeling 90 percent better. Now this.
I hear you about resting it, but if you saw my stove, you would have spanked me to get on cleaning it.
It feels like the bone though, not the muscle that is how deep the pain feels.
