Hello,
My 83 yo mother has had facial swelling and puffy eyes,for about two to three weeks.She takes medications for blood pressure and heart failure, fluid retention and a blood thinner.She was also treated for scabies several months ago, and had a skin scraping which detected no scabies,but she continues to get more of what appears to be scabies type skin eruptions mostly on her back.They are very itchy and she picks at them and scratches most of the time.
