Hi Zakria.
I am glad you found your way here.
You say the wound is healing o.k.
did you take any antibiotics? The start of it sounds like an infection of some type. have you seen any doctors or the dentist since this started??
I dont recognize the symptoms you mention .. twitching in arms hands....usually it is the face as far as T.N.
I am not a doc or a pro but I think it is more on the dental end or an infection ..maybe the saliva gland is clogged . twitching.. did you have neck injury when they were getting tooth out? pinch a nerve??
I see you posted this in the dental forum also good job I bet you will have some better answers and be in the right direction soon.
keep us posted and let us know how things are. and if you are in a dark place we are here , your not alone. if your in bad bad pain go to emergency room.


PEACE
