Pain
"I have  Frozen Shoulder (Adhesive Capsulitis). Aspercreme (Trolamine salicylate) had the least/mildest side effects of any other medicine I saw, and the price was great.  My mother had a frozen shoulder around 1985.  Surgery was recommended, but she wanted to first try the painful stretching exercises to break the adhesions.  This helped ease the pain enough to do them and recover.  Since then, I have used it occasionally for a cramping deltoid muscle in my neck/shoulder that would send me to bed otherwise.  Works really well when Tylenol is not enough, especially when trying to sleep."
