You should consult a medical professional.  There are lots of illnesses that could cause those symptoms, but it's better not to self diagnose.

There might be a medical reason for it, so see a doctor to be safe.

it could just be a bug bite, or like some have said an ingrown hair, if you shaved like right before you did things with that guy, but still go to the doc, and ask, its not that hard, and it only takes a few min, teehee

Been in your shoes many a time....waking in the night horrendous nightmares, insomnia just not knowing what to do.\nI really empathize.\n\nIt's hard when your mind seems to be going nowhere in particular just having random rotten thoughts and you wonder how long can it go on this time?\n\nIt is hard for people to understand this kind of illness unless they've been through it themselves.  It's like you've entered a room that most people have never seen before and never will and you try to describe it to them...they get the picture...but they don't actually FEEL and THINK it.\n\nBe kind to yourself to try to balance things up a bit.  Treat yourself to comforts that you need at this time.  \n\nPeople used to say to me...'you'll get there' or it'll pass, but it's while it's happening....what doyou do then?\n\nDo you journal your thoughts?  I do.  I write down very quickly all the things that pop into my head in the order that they come, just scribble them down as fast as you can.  Make sure you write EVERYTHING that comes to you.  Then when you think you've finished, read aback through what you have written and you'll find that the things that are getting to you the most are near the begining....try to resolve some of these.   If you're like me, the page may be full of dunnos!\n\nGive yourself some rest today and don't forget to treat yourself in some way - even if it's a relaxing massage from someone you trust.\n\nBest wishes.

Well he could be psychotic, or he could not like you very much and is playing a game or he could be a skitzo or he could've gone through some major trauma and have head problems either physically or now he just has skitzo tendancies or he could be this- DID YOU KNOW THAT MEN HAVE HORMONE CHANGES EVERY HOUR? THAT MUCH LIKE OUR MENTRAL CYCLE THAT HAPPENS ONCE A MONTH WHERE OUR CHEMICAL BALANCES CHANGE THEIRS CHANGES 24 TIMES IN A DAY-it still doesn't give a guy a reason to be a jerk!

Sounds like a pinched nerve, (which would constitute the numb feeling and unable to move it as done before( get it checked out.

There are no nerves in your brain, so it is not your actual brain. I would talk to a doctor if this is seriously bothersome.  My first thought was mini stroke or aneurysm

A nerve impulse in the brain it is not easy to control so talk to your doctor about it.
