Breast reduction yesterday morning. No drains. Hot burning sensation to left breast scull art. When I get up or turn my body?

Congratulations on having undergone the breast reduction procedure. Whether or not what you are experiencing is a "normal" part of the healing process cannot be determined online. Your plastic surgeon will be your best resource when it comes to an accurate assessment, advice, or meaningful reassurance. Follow up with him/her with your concerns; preferably see him/her in person, earlier than already scheduled, if necessary. Best wishes.

Thank you for your question and
congratulations on your surgery! After a reduction the nerves of the
skin are stretched as a result of swelling and the tightening of the skin once the breast tissue has been removed. This stretching irritates the nerves which can cause a number
of different nipple and breast skin sensations including increased/decreased
sensitivity or a burning/electrical feeling. These normally resolve
spontaneously given enough time. Hang in there and be sure to
mention these issues to your surgeon during your post-operative appointments.

It's hard to say what's going on without photos and more information.  Although burning sensations are common after surgery, it is important that you contact your surgeon to inform him or her of any changes to your condition. Good luck.
