Symptom narrative

About two weeks after receiving his MMR. Parents observed an overnight change where he started self-stimming pretty heavily. Palms to ears while vocalizing and beating hands against ears, fidgeting with his ears, repetitive phrases, jaw clenching with lateral shifting, fingers flicking, escalating quickly within the first week. He was distracted by the stimming that they couldn't get his attention, he became very aware of sounds in general. He became preoccupied with lining up dominos, not anything he did before. He is reactive to fatigue, excitement and upset, started toe walking, he got more physical by ramming head into moms body and responding to deep pressure.

Lab data

No medical tests or labs. Mom has been working with him on handling sounds, some symptoms extinguished others are showing up. Parents implementing a sensory diet. Seems to decrease stimming to less frequent and more self calming.
