Sharp excruciating muscle pain. Doctor.

I'm only 18, and I keep having a sharp, burning, excruciating pain when I move to fast. This meaning everywhere. Example; I went to pick up my little 2 year old niece and this feeling started happening in my collarbone/armpit area (this is normally where it happens.) Usually only lasts for a minute or two. It hurts so bad it brings me to tears and I have a high pain tolerance. When I'm at school and I raise my hand to ask a question, that feeling comes, and I'm a shy person but I can't help but to groan in pain (which I would never do if I wasn't in serious pain) sometimes it also happens in my hips or legs. I don't know if it's a muscle pain or something of the sorts. Just wanting to know if there's a name for this and if I should go to the local doctor. Thank you in advance.
