The first thing is to see if you have suffered any trauma. If there is no trauma, but suddenly it hurts so much that you wake up at night with pain, it is possible that there is a calcified lesion in the shoulder; or if there is inflammation in the shoulder joint or a bone spur, especially if it does not hurt when you lift it, but hurts when you lift it to a certain angle, it is very likely that there is a bone spur. The treatment of calcified lesions can be found in my series of articles, while long bone spurs need to be treated conservatively or minimally invasively by drilling three small holes with special arthroscopic instruments to polish off the spurs depending on the severity of the situation. Then there are patients with traumatic injuries, such as pulling hard, carrying heavy objects, having the bladder pulled by others or direct impact, etc. The pain in the bladder is not obvious, but it is impossible to lift. Or, if you can lift a little, but you can’t hold it up for a while, it falls off. In this case, it is possible that there is a tendon injury in the shoulder. In younger patients, the tendon may have been damaged by trauma, while in older patients, the tendon may have degenerated itself, and with a little external force, the degenerated tendon may have ruptured or partially ruptured. Most of the time this happens, the injured tendon needs to be repaired and sutured under the arthroscope using special suturing instruments. In short, there is always a reason why the bladder can not be raised, it is best to be able to clearly diagnose with the help of a doctor, never easily swing the bladder exercise, like the first case with bone spurs can not be bladder raised at all, the result of swinging the bladder hard is that the bone spurs continue to damage the tendon until rupture, transforming into the second case is more serious.
