I've got speech backs too. As child I didn't have speech blocks. I had different stutter. It took me one year to encourage to start to do something about it. I have tried hypnotherapy, now I'm trying somatic therapy. I have tried acupuncture. For about 2 weeks I stuttered much less. I'm thinking to give a try again for it again. If it would have the same impact on me the I would do it weekly. Hopefully the repeats would make a change. Do you have any physical symptoms? I've got muscle jaw tightness. Which is the symptom of stress or may can be PTSD.
