I felt stiff shoulder in the afternoon yesterday after a long while. I think it was cool air caught my neck and having coldness. So I wore scarf around neck and shoulder. But soon I felt hot and removed it.
It was my weakness which I can’t control my temperature well. It’s hard time for me to face the changing temperature from hot to cold. I might be very careful in the beginning of fall which usually causes me problems in my back.
I have to start physical exercise, stretching, shaking scapula and winding arms.
