I am writing on behalf of elder sister who is suffering from myasthenia gravis. Her age is 29. Since last 17 years she have been facing these neuro disorders. Sometimes it happens twice in a day, or once in a month. When it happens it lasts hardly 1 to 2 mins. During the incidents she just become absentminded.... and pressing her fingures....now she is ffacing another difficulty of weakness of all muscles. Drs are saying to operate, however there is no positive result in HR CT scan. Found positive results in acetylecholine receptor anbody test. Want to know what is risk involved in operation (after operation).... Will she be fine after operation. What are the best treatment for it. Is life threatening in future? Can she go for marriage life?....firend please me to take care of sister. Quick repons appreciated!
