After the patient's second dose, she didn't feel right; it was much worse than the first. She started getting sicker and sicker and her Pott's disease flared up. Two weeks to the day of her second dose, she hit the wall of the worst she ever felt; felt like she was going to drop dead. She went to the emergency room (ER). She could feel all her organs and feel the adrenaline coursing through her body. She felt like laying down but couldn't breathe right. She felt like she was being pushed down at all times. She could barely walk, was shivery, shaky and trembling. It was the worst autoimmune flare up in her entire life. The ER didn't really know what was wrong and thought maybe it was because her levothyroxine (SYNTHROID) had been adjusted. She felt a little better a few days later but the veins in her hand were bulging like a weight lifter and hurt very bad. She followed up with her doctor 6 weeks after her first dose. The patient reported it was still hitting hard and she couldn't function like a normal person. Her period was late and her body went haywire. Treatment information was not reported.
