Thanks for your question
in family is a risk factor for these illnesses, and your family life is also not on good tracks, and you have been recently diagnosed with PTSD. Its really very painful and I can understand your state of mind.
The problem in your question, that is scratching sound in your head may be due to many reasons-
- most likely possibility is severe anxiety
, as you are going through a difficult phase and in such stage a person becomes highly anxious and this increases his vigilance or he becomes hyper vigilant. So any normal thing is mis interpretated. Some times without any reason one may start hearing scratchy noise or may see shadows or a become fearful. Its not a true hallucination
. Depression associated with this is also increasing the risk
- Second possibility is any psychosis
, but picture in psychosis is very different and voices in such cases are clear, demarcated, and usually threatening voices. But you have family history of SCHIZ still as per my opinion its not on psychosis side.
Regarding management you are taking right drug Celexa or Escitalopram, but addition of some anti anxiety medicine like clonazepam
may help to relieve acute anxiety and will also help you in getting proper sleep. So try to get rid of bad time as soon as you can and take proper advise of your doctor.
Hope I cleared your doubt.
Thanks, take care.
