I find his sensitivity interesting because it happened at the same time and is confined to the back, tricep area, and saddle area. Going to call our GP in the morning to get him set up for xrays and MRIs before moving on to the neuro.
Our son is going to a PEDIATRIC neuro tomorrow to investigate his seizures (he is also T1 Diabetic). I believe our house is cursed.
