Any suggestions on what this could be and how I should move forward?

Recently, I have been having some odd symptoms that have me confused. I have looked online to try and get an idea of what it could be but I have been unsuccessful. The symptoms that I have been experiencing are: involuntary twitching or ticks of the muscles around my mouth when I'm talking (it's not all the time but happens at least once a week), the twitching of my mouth is accompanied by minor vocal abnormalities (as if my voice is twitching too--will make short sounds like 'eh'), little muscle twitches or spasms in various other parts of my body (mainly in my shoulders, upper arms, and thigh area), ticks at the base of my head or in my neck (these make my head jerk suddenly back or to the sides slightly). I believe I was anywhere between the ages of 11 and 13 when these symptoms started. I am 20, almost 21, now. When they first started, I only noticed the spasms around my mouth when I was reading a book aloud or something and it was rare. It only happened once or twice in a year--not really enough for me to notice but enough to be annoying. Over the years, I've noticed there are more symptoms present and they are more frequent. They have gotten especially worse here recently with an increase in stress (I'm in college). When the symptoms first started, though (and any other time except recently), I wasn't stressed at all. I have not mentioned any of this to a doctor yet because it hasn't bothered me or concerned me until now. I realize I have a lot of information here but does anyone have any suggestions as to what this could be or what I should do/say when I talk to a doctor about it?
