I Am A 19 Yr Old Female Who Is On

I am a 19 yr old female who is on the college track and field team. I have these weird twitches/cramps that have been occurring all over my body. My nose will feel like it is twitching randomly. The side of my left hand will cramp up and form a line or indent in my skin. My neck will cramp up when I get dressed. And also just other random spots will twitch from time to time like my chest near my heart, or my leg, my eyebrow, or eyelid. I was experiencing this last spring and it progressively got worse until I went home to for summer vacation, but since I have come back to school they have started up again. I was working out over summer so I don't think it has to do with working out. Also my period is very consistent but last spring when I had this going on I missed one and I am late right now. I drink plenty of water, eat a verity of food, and don't take any medications. It is also not from caffeine because I stopped drinking coffee for 9 days and the symptoms did not go away. Is this something I should be concerned about or is there anything that can be done to prevent these symptoms?
