PTSD is not about feeling feverish, kicking out of legs and arms to cover oneself nor does it have to do with muscle spasms....

PTSD stands for Post Traumatic Stress Disorder..

it is a cover all labeling for a group of symptoms...having panic attacks (which is a group of symptoms together of having trouble breathing, heart racing, extreme fear, ) flashbacks (literally reliving a traumatic event as if you are still going through that trauma) nightmares about the traumatic event, intrusive thoughts and memories about the traumatic event, intense or prolonged distress about the trauma....

the new Diagnostic criteria for PTSD is that in order to be diagnosed with PTSD and its related symptoms/problems in the USA

Criterion A

the person must be able to remember being in direct exposure to the trauma, or remember they were in direct exposure by a witness to a traumatic event, or indirectly by being affected by someone else that has been through a trauma, or have been through trauma indirectly or directly through being a professional ie police, fire fighter,therapist.....

criterion B

Recurrent, involuntary, and intrusive memories. Note: Children older than six may express this symptom in repetitive play.
Traumatic nightmares. Note: Children may have frightening dreams without content related to the trauma(s).
Dissociative reactions (e.g., flashbacks) which may occur on a continuum from brief episodes to complete loss of consciousness. Note: Children may reenact the event in play.
Intense or prolonged distress after exposure to traumatic reminders.
Marked physiologic reactivity after exposure to trauma-related stimuli.

Criterion C
avoiding thoughts, feelings, people, places, things associated to the traumatic event.

there's alot more that goes into this...here is a link where you can read the full wording and diagnostic criteria for having PTSD.

though with some people they do have repression problems (repressing a memory) they know they have been through a trauma and can remember parts of that trauma ie what happened before the trauma happened and what happened after and bits and pieces in between when the trauma was not as intense as other parts of the trauma...

here is what PTSD looks like with in me....

I was abused as a child in a mine shaft. I could remember being in the mine shaft, remember the smell of being in the shaft, remember being afraid of the dark....what I could not remember was the actual abuse. I knew something bad had happened but not what. after the abuse I remember being in great pain and avoiding the mine shaft, my abusers, I avoided the booze isle in the store, refused to wear the same color and clothing that I had worn during the abuse even though those clothing had been laundered, I couldnt even fold those those off the line because it would trigger me to have a panic attack. at night I had trouble sleeping due to nightmares, I would go out of my way to stay awake so that I would not dream about being in the mineshaft being abused.

when hurricane Sandy happened and for months afterwards I would have panic attacks, nightmares and flashbacks every time a storm would come. didnt matter that it was just a normal rain storm in my mind we were going through the hurricane all over again. fear of losing my home and all...

Muscle spasms and feeling feverish are physical symptoms of things like having a cold, flu, other physical illness or a neurological disease like I have multiple Sclerosis (a physical health condition where the covering on my nerve cells are degenerating/failing) this causes me to have all kinds of physical symptoms and sometimes mental too.

fevers and feeling feverish is usually the body's way of fighting some sort of infection/virus...

my suggestion if this continues to bother you contact your medical doctor and a mental health treatment provider who can do some tests to evaluate why you are getting muscle spasms and fevers/feeling feverish and other symptoms you posted about.
