My age is 28, from West Bengal. I have been stuttering from my 13th years age. Particularly few syllables causes stuttering. Initial letters, syllables block more in speaking. Feel ache at chest and throat sometimes while speaking. Jaw vibrates and feel lack of energy. Earlier I spoke very much, fast, clearly and fluently. Normal voice causes stuttering maximum. In very lower voice with pause and in excited mood no stuttering found. Please identify the exact problem and remedial suggestions. I will remain grateful to you for ever.
