Take a break, and if it goes away, mention it to your doctor next checkup. If it doesn't go away, go see a doctor right now. Everything you do online in regards to diagnosis must be either for entertainment, for possible simple remedies that are next to 0 risk (If an icepack might help according to the internet, why not try an icepack if it can't hurt), or to see if people say that this symptom could be a indicator of something serious to get you to go to a doctor immediately. Basically, diagnose away, assume that you are almost definately wrong.
The one time I diagnosed myself, the emergency room doctor stole my diagnoses, charged me 700 bucks to tell me to keep taking advil and go get a physical, and my regulardoctor told me why my diagnosis didn't make any sense whatsoever.
