Hello Vamshi, there are many types of therapy that have been helpful for different people with PTSD from complex trauma.
Craniosacral therapy has been very good for some people, I believe, and a calming practitioner who is trustworthy would be important for all therapies. I also know people who value acupuncture, reiki, and trauma-sensitive yoga (as I understand it, yoga in the U.S. varies greatly and many can be very different from any yoga done in India; in the U.S. some people use it for exercise, but I have heard that the traditional breath-centered parts might be more helpful for PTSD). Calming, breath-focused yoga and other traditions of meditation have been helpful to many people. Scientific research has shown certain types of yoga to be helpful for military people with PTSD. Painful therapies are generally *not* helpful since our brains are already having trouble with basic "fight or flight" regulation.
Craniosacral therapy, here, is likely called a "complementary therapy" (like massage, acupuncture, restorative yoga, etc.); professionals would call the "talk therapy" the primary therapy. However that is really based upon our country's history of mental health treatment techniques rather than objective science, in my opinion.
Many of us need *several* types of therapy over time, since the trauma affected many aspects of our selves; one can try one type for a while and then feel a need to do a different type. Our bodies, spirit/emotions, basic feelings of safety, and "higher" cognition are all often affected. You do not need to do everything at once, though, please give yourself time and patience.
A therapist who is a psychological practitioner with specific training in trauma /PTSD is extremely helpful to a lot of us. However the research and therapies have improved a lot during the last 15 years, so a therapist with recent training can be very helpful. I don't know what names people might use for therapies in India; every country seems to be different! Maybe someone else familiar with India will answer.
Here in the U.S. we have "Clinical" Psychologists, Clinical Social Workers, etc. who work with people and study mental health therapies (especially talk therapies, andy many use several types of talk therapies depending upon their patient -- in most cases.). "Psychiatrists" here are medical doctors trained in brain chemicals/medications etc. but also a little bit of talk therapy.
Theories to explain PTSD have improved greatly in recent years, and now brain scans of the brain function using MRI machines support the existence of the physical/neurological/electrical effects of PTSD... I feel like this has helped sufferers here since science-minded doctors and therapists no longer can deny the existence of types of PTSD. (Although some still do!!! if the doctor is ignorant of the research, dislikes the ideas and avoids related research, never questions themselves, never updates their learning... :rolleyes::( )
I think that the training is part of it, but one needs to be able to feel some sense of trust in the therapist; many of us feel helped by warmth, empathy... not just scientific expertise or any one therapy. The combination and growth is the best for me... I believe our brains have to grow to heal.
If I have misunderstood your question, please ask more questions! Please ask more questions even if this answered your current question. You can also search these forums and help yourself to frame more questions; I do that a lot. There are many wonderful people here from many countries. :tup::hug:
