The right clavicle hurts for no reason.

Suddenly, I haven't done any exercise, and without any particular reason, my right collarbone hurts very badly.

Then the pain started to spread up to just below my chin. It doesn't seem to be a bone problem, but I wonder why only the painful areas keep increasing. Getting older is upsetting enough, and now I have to deal with this pain too. ㅠㅠ
