It's been third day since I feel tightness in my right upper part of my collarbone.
I've been stressed lately and overthinking everything.
Feeling ball-like thing in my muscle. Is this an artery?
It doesn't bother me if I don't think about it. Visually, it's not visible. When I press my hand there, I feel it. Same thing on the left side but this ball-like thing is not as big as the one on the right.
I don't think it's a lymph node because it's in the center of my shoulder muscle.

Area marked with X is where I feel this ball like thing.
I lifted weights day before I felt it.
It was tighter yesterday and day before yesterday.
It's not painful.
