Hello Just J,
My Mom has been extremely cold. We were sitting outside in the sun yesterday, (NY--78 degress). Mom wore a sweatshirt and had a blanket. Not sure what PLS does to your body temp. My Mom has lower back pain, leg pain, and her arms. You cannot even touch her lightly on the arms, bec. it is painful. You are not alone. Try to live one day at a time. The people on this site are so helpful and kind.
