Hi, I am a health person, but 3.5 month ago, I started having BAD hives. They are very painful and spreading into all parts of my body. I saw a great immunologist and he ordered a lot of blood work. Nothing showed up, not even allergies to oak, grass, dogs, etc. No immune system problems.... he gave up and sent me to the dermatologist. They took a biopsy from different parts of my body and I am waiting for the results. I am worried that they will not find anything and I will be in pain forever. One thing that comes to mind is that the blood work showed some inflammation. The immunologist was not worried about, but the student who was taking my biopsy said that it looks like my body has been dealing with some bacterial infection. The only thing that comes to my mind is my tooth where I had an abbess twice already. Around the time when I started having hives, I had my braces installed and I was told by an orthodontist that the infection is showing up ( no pain, yet from the tooth). Is it possible to hives from the tooth cysts? Thank you. Anya
