Update, I have been lifting weights for a month now since I was feeling good but I think it is too much for my CNS as I have had some mental sx come back. This is very frustrating and I guess that proves that I am not healed.
I know how frustrating this feels, I think sometimes all of our symptoms clear up and our body's still have a bit of "behind the scenes" healing to do that we just don't see or feel. I personally believe that more people then we know deal with this, their body's just may not be tested to the same degree that others are with lifestyle changes (exercise etc), meds needed for health reason like antibiotics, or severe forms of stress.
I don't think that this at all should take away from all of the amazing progress that you have made or from the fact that you are basically DONE with this shit. Push on, don't let a few shitty symptoms take away from the feeling of being at the end of this.
