I don't know the answer to your question; but, I do have some thoughts. A poor night's sleep can be caused by many things but sleep apnea is one of them. Sleep apnea can be responsible for many health problems possibly even your weeping edema.
With regard to the edema, I pray you are visiting a doctor to help cure this. Weeping edema can be a very serious problem. Pay particular attention to cleanliness around your edema patches. Use a gentle, natural cleaning product to keep the moist areas clean and dry.
