I am male 21 studying in 3rd year mbbs. i have been diagnosed with intentional tremor.doctor prescribed me medicine but its not doing much.so i have question.does intentional tremor go away if so in how much time.if not it worsens should i leave mbbs?

Seems like the issue is more of Anxiety for a 3rd year Medical Student at age 21. Good idea to do Stress and Anxiety Reduction Exercises, See a trusted PCP/Counsellor and if indicated have a Neurology Consult as well. Once the appropriate and correct diagnosis has been made, the appropriate Specialist will have no problem helping. Sounds more like Med School Jitters. Hang On!
