This is a pain or weakness from an irritated nerve in your shoulder. It's called the "suprascapular" nerve. It travels from the neck down through your shoulder.
Suprascapular neuropathy is caused by irritation of your nerve. This can happen because it's stretched or compressed. A poorly-shaped shoulder blade that doesn't leave enough space for your nerve can cause it. So can a cyst pressing against your nerve.
Symptoms can include pain over the top and back of your shoulder. Your shoulder may feel weak. Some people have shoulder weakness, but they don't feel any pain.
Treatment options may include rest, medications and physical therapy. If these aren't helpful, you may need surgery. Your healthcare provider can create a plan that's right for you.
