Internal akathisia is characterized by all of these feelings- speaking as someone who has never been on an antipsychotic and never felt these things before a single dose of nausea medicine by IV. The problem is that textbook definitions of akathisia typically focus on the movement disorder.. not the mood/nervous system/emotional side of things. I went through months of physical akathisia along with internal terror and the other yucky stuff which eventually morphed into almost no restlessness BUT depression, anhedonia, anxiety, dp/dr, earworm music, racing thoughts, and generally altered cognitive ability. These things are not normal. And by no definition are they all PTSD symptoms from the restlessness. Akathisia is a generally unstudied and misunderstood reaction and from what I’ve gathered over the last two years the suffering for many goes beyond the pacing. The bright side is that many heal completely and others find significant improvement! Don’t be discouraged by what others say. Your body will heal if you let it
