Swelling
Along with the pain and discomfort around your shoulder, there might also be redness and swelling. This would suggest the presence of bursitis or injury. Bursitis happens when the fluid sacs that are responsible for cushioning your muscles, tendons, and bones around the joint get inflamed. Chronic or short-term flare-ups would cause the shoulder to swell, hurt, and turn red over time. In most cases, resting would help the flareups subside over time. But if the symptom keeps coming and going for an extended period, it is better to consult your doctor for better treatments. [2]
