This is not bad. My husband used to use this to fix his shoulder circumference. Husband driver, driving for a long time, is prone to scapulohumeral periarthritis. I ran a few long-distance races, which was very uncomfortable. At first I covered it with a hot towel, but it didn't work very well.

Later, the doctor gave me this old epaulette, which is quite good. I posted it for a month, but the doctor told me to let many families do more exercise and activities instead of sitting for a long time. I hope it helps you.
