Hi, so I'm 19 and I was talking the phone and I put it between my ear and my shoulder while I washed my hands and then as soon as I moved my neck from that position the pain set in. It got so bad that I had to lay down because I couldn't even catch my breath. I laid down for a while and the pain got way less intense. A couple days passed without any pain and then I was playing basketball (something I rarely do), and then I took a shot and it happened again but worse, couldn't breathe and had to sit down for a while. Now a few days later the pain isn't bad, but I can still slightly feel it. Any suggestions?

P.S. Most of my physical activity is biking a mile to and from class everyday and lightly exercising a couple times a week.
