I know many of us have issues w/our nervous system. Is there a medication that helps w/these issues? Specifically targeted towards these issues? Or is it just "Here, we'll try this and if it doesn't work then we'll try this"? I know there's nothing specifically geared toward brain fog, but what about the other issues? ie: numbness, burning tingling, heavyness of limbs, having to REALLY concentrate on moving said limbs (lol), etc.....
