the eye twitch - definitely . i experience it whenever i get stressed. it's a bloody bugger to put up with!! especially when i'm trying to read stuff for uni. i also find my accuracy with typing goes out the window at times like this.

the numbness/tingling i have put down to have poor blood circulation. if you are small like me, apparently it is a well known problem. my doc has suggested making sure i stay well hydrated and also exercise often. it tends to help.

the deep pain/bone pain thingy - this will sound weird, but (for me at least) it's associated with high humidity. i use it to predict rainfall (no joke). a lot of people have it, but i think it depends on what area you come from and if you share the same genealogy.

sorry if none of this helps - but the eye twitching etc can be explained by stress (just make sure you've also had an eye test though before you dismiss it entirely).
