Back attack!!!

Patient: I have recently had injury to a rod through my pelvis.. Since this my body has been in kind of a healing state and tends to give me syatic problems, and has built a flud pocket that I’v had to have drained called a “soroma”?? almost 200ml worth!.. They told me my body could be in a state of rejection with the rod.. But here lies my question.. In the days im in the most of the pain and i try to sleep i tend to sweat alot and im not too sure why?? Like wake up wet like my body had been fighting off a bad cold…

Doctor:
