Good afternoon! I am 24 years old female, since last two week I noticed pain in my shoulder generally when I wake up in morning. The pain is bearable and vanishes within few minutes. Following are my questions and situations:- 1) is this pain due to bad posture of sleep or something else? 2) suggest me how can I avoid this pain situations:- I tried to sleep the way google recommends using pillow between legs and beneath legs but it didn't worked because I found my self in wrong posture and whole my bodyweight goes on shoulder.
