My herx symptoms that I can think of: foot pain, joint stiffness, stiff neck, abdominal pain, electrical pains in my head, burning scalp, numbness, burning pain in tissues, bouts of anger, rage, irritability, feelings of despair and wanting to die, sudden crying, anxiety, worsened chemical sensitivities, sensitivity to light, sound, motion, smells, headaches, trouble sleeping, feeling like my brain is inflamed or on fire, trouble with balance and coordination, trouble remembering, difficulty with words and speaking, getting confused, exercise intolerance, unable to handle stress, feeling allergic (sneezing, itching, twitching).
