I am taking medicines of bipolar depression since 2012. I am attaching the prescription of medicines that I have been taking since 2012. In 2016 after passing class 12 I found out that I was not able to write with my left hand. Since childhood I have been writing with my left hand. Since 2016 I am not able to write with my left hand. Whenever I try to write with my left hand my index finger gets slip from the pen. I am not able to grip the pen firmly. I have consulted a lot of doctors. But no one is able to identify the problem. They adviced me to write with my right hand. I want to know my problem in my left hand. I am not able to more than one prescriptions of doctor.
