I have a shoulder problem where a certain part of my anterior delt gets extremely fatigued for no reason whatsoever. I have a feeling this has to do with mobility issues as my body is entirely asymmetrical (right side of body is dominant in every aspect) and this is only affecting my left shoulder.
I cannot perform forward arm circles for more than 10 seconds without my left anterior delt experiencing incredible fatigue. If I stretch my left delt, I can hear my tendons/tissues/etc inside my shoulder crackling and make popping noises.
There is no pain yet, but I feel if I let this keep up there may be pain in the future. Does anyone know what the problem is and how to remedy the issue? I am trying to avoid seeing a physical therapist at all costs since I am a poor college student but If I have to I will.
