Why is One Breast Softer Than the Other 1 Week Post-op?

You just have to be patient and give your breasts time to heal.  Since you had asymmetry, more work was done to correct your breasts.  Healing times are not equal on the right and left breast.  The burning you are feeling is typical in healing.  It may be nerves healing.

After a little more than one week since your surgery it is common to have a little asymmetry. Some of this may be related to the surgery, though most of this is due to your pre-surgical appearance. If you start with asymmetry of your breasts before surgery you will most likely have asymmetry after surgery. Having an augmentation alone does not allow the surgeon to make changes to the shape of your breasts - only the volume. Also, it is very early to judge the end results. I would recommend that you wait at least three months from your surgery. If you are not happy in the end, you can always choose to have another procedure to reshape your breasts in the future.

I hope this info helps!
