  2. My wife has had these weird pus/blood-filled bumps on her inner thigh for years. She got diagnosed with hypothyroidism, and she decided to go an alternative diet to try and fix it. The diet didn’t fix her thyroid, but serendipitously it made the bumps go away! She thinks it was white potatoes causing them, but not entirely sure. It was the Autoimmune Protocol (AIP) diet.

  3. I have had a bump form on my knee for a few years now. I had it X-rayed and the technician said that they could see a small metallic object under the lump. I was sent to a surgeon and he told me that he can’t see any objects in the same X-ray that the hospital tech took and told me to go to my GP and have him remove it in his office. I now think it is a tumor and I don’t want it to go on too long. My doctor says he doesn’t “think” it is a tumor.
