Encephalitis vs. Brain Inflammation: What's the difference?

I’ve been dealing with these persistent issues for about a month now—elevated body temperature, headaches, aching in my arms and legs, muscle twitching, and even some numbness. I went to the hospital, but they couldn't find anything definitive; however, an MRI of my brain did reveal some scarring, suggesting I might have had encephalitis at some point in the past. One doctor suggested that all these current symptoms could actually be linked to that old brain damage, though another physician is arguing that isn't the case. Does anyone here have any firsthand experience with this, or perhaps some insight into whether these things are truly connected?
