Hi, my 8 year old son has just been diagnosed with suspected PANDAS. I had a severe strep infection approx 2 months ago and was treated with 10 days Penicillin. Approx 2-3 weeks later my son had vague stomach symptoms, severe irritability and had a panic attack when I touched his neck. His fear and panic was so severe I got him to urgent care, a throat culture was done even though he didn't have a sore throat or fever. It was positive, he was on 10 day of Penicillin. Unfortunately his panic, fears and phobias increased and he has become anorexic from a fear of choking. He has had a psychiatric eval and she feels he has PANDAS and started him on a very low dose of Zoloft. It has been 7 days and no improvement. It has been 6 weeks since onset of symptoms. At this point what should I be asking his doctors for? Does he need another strep test, do I need another strep test? Should he be on a longer course of antibiotics even if the strep test is negative. Any advice would be helpful.
