I understand the problem of twitching is creating psychological and social problems for you.
One reason for the problem could be the trauma, which could have caused damage and exposed the nerve
endings, which are being stimulated by minor stimuli also and causing you twitching. Another reason could be electrolyte imbalance
in the body fluids, especially calcium levels and lastly it could be habitual. In my opinion you need psychiatric help for your well being and secondly careful application of Botox
by an expert may help you.
