My name is Matt and i am 20 years old. I have not had any problems with this until i was in my early teens and it progressively has gotten worse. it first started off as every little noise would make me jump as a cough, sound, bang, etc would make me jump a mile. When i was in a school classroom i would sweat and try to tense my body to make it stop, my body would feel as if it wanted to have a seizure( i have never had one). My body also would twitch when i was giving presentations and trying to talk in front of people. This was really embarassing and was hard for me in school. Now it seems to have gotten worse, i can hardly use my right arm and when i dont use it i hold it to my side, my mom says it looks like i had a stroke when i hold it there but i can't help it.It does it a lot when i am in public because of the noise.Also, now it seems i can't even talk to people. when i try to talk to people i either stutter a lot or i lock up and can't say anything. It is hard to talk to people on the phone or even go anywhere. My girlfriend or mom has to order my food when we go out to eat. I forgot to mention that it effects my writing, i used to be able to write but now i try to right and my hand bounces all over and i have to clench and tense my arm to be able to write. If you have any information for me anything would help. i just want to know what i am dealing with and if it is treatable or not. Thank you.
