Sore shoulder. Hurts when I put full body weight on right arm, reach for things, throw & when I lift arm out and up it makes a pop when I lower arm?

Be seen. I sure would not hesitate to be seen. The three most common causes are an injury to the rotator cuff, the labrum, or the ligaments that stabilize the shoulder. An exam can give a good idea about wether or not it is serious.
