Is there any effective treatment for ptsd?

Holistic approach. Ptsd is a whole body tragedy, with massive repercussions. An excellent resource is the book: the trauma tool kit. The trauma tool kit maps out stages of healing from stress-related disorders and provides immediate first- aid techniques that help alleviate the most intense symptoms of traumatic stress in a small amount of time. It combines modern neuroscience and ancient healing to help recovery.
Meds psychotherapy. Get a full psychiatric evaluation to assess for PTSD symptoms, and see if medications are warranted. Next, find a reputable psychotherapist nearby who specializes in PTSD. Generally speaking, meds and psychotherapy together are the best approach.
