Hello all. I am about 8 weeks postpartum with my second child. for the past 4 weeks I have experienced a sunburn like sensation without skin changes over various parts of my body. It started in the back of my left neck and arm, then spread to the other arm, and eventually most of my back, thighs, feet, and most recently ankles. It is rarely present in all of these areas at once and varies in intensity. Nothing seems to affect it - temperature, activity, positioning, etc.
