thnks evryone for your support...
2 days back i had soo much pain that i was not able to open my mouth..my jaw hurted a lot.
i went to a dentist.he said i hav an impacted wisdom tooth..which can probably be the root cause of all my pain because people dont get TN at such a small age....so i ll wait some more days to check if he is all correct....hoping for the best
