It's not really focused on but Lupus can cause muscle pain and such as well. I notice that my shoulders burn a lot, but that's about
my only area I notice burning, all my other joints and muscles just ache. I'm sorry your going through this ]:
If you haven't been diagnosed with lupus and you suspect it, I suggest going for blood work while your in a flare or with the butterfly rash if you get that. My tests always came back negative until I went in with the butterfly rash and the test came back positive. Lupus is sneaky.
I really hope you feel better and get some relief from this pain, hopefully your doctor will start you on some medication quickly. Until then please take it easy ]:
Feel better soon.
